sdmbin::BaselinesSet::BaselinesSet ( )

sdmbin::BaselinesSet::BaselinesSet	(	std::vector< asdm::Tag >	v_antennaIdArray,
		std::vector< int >	v_feedIdArray,
		std::vector< int >	v_phasedArrayList,
		std::vector< bool >	v_antennaUsedArray,
		DataDescriptionsSet &	dataDescriptionsSet
	)

Definition of the second level of the tree hierarchy.

Precondition: the lower levels of the tree hierarchy are already known

Parameters

v_antennaIdArray	Array of antenna identifiers
v_feedIdArray	Array of feed identifiers

Note: Because with ALMA there is only one feed used at any time this vector has the same size as v_antennaIdArray. With Focal Plane Array this size is multiplied by the number of feeds in the FPA

Parameters

v_phasedArrayList	Place-holder, not yet implemented
v_antennaUsedArray	Array to tell in the antennaIdArray which antenna have been actually used for the data being stored. v_antennaUsedArray and v_antennaIdArray must have the same size.
dataDescriptionsSet	a dataDescriptionsSet object (i.e. the lower levels of the hierarchy

Postcondition: the whole tree hierarchy is now known, transfer identifier available for read and write methods

Note: v_feedIdArray may be typed vector<vector<int> > in the future to better describe the case of of focal plane arrays when used with interferometers

sdmbin::BaselinesSet::BaselinesSet ( const BaselinesSet & )

Member Function Documentation

unsigned int sdmbin::BaselinesSet::antenna1 ( unsigned int baselineIndex )

Antenna index of the first antenna of a pair defining a baseline number.

Parameters

baselineIndex A baseline number (zero-based)

Exceptions

baselineIndex not zero-based

Returns: the index for the first antenna of the pair in the list of antennas effectively producing data

Exceptions

Error if there is no such baselineIndex in the configuration.

Note: See the note in the documentation of the baselineIndex() method to know how baselines are ordered and how baselines correspond to pairs of antenna indices.

unsigned int sdmbin::BaselinesSet::antenna2 ( unsigned int baselineIndex )

Antenna index of the second antenna of a pair defining a baseline number.

Parameters

baselineIndex A baseline number (one-based)

Exceptions

baselineIndex not one-based

Returns: the index for the second antenna of the pair

Exceptions

Error if there is no such baselineIndex in the configuration.

Note: See the note in the documentation of the baselineIndex() method to know how baselines are ordered and how baselines correspond to pairs of antenna indices.

unsigned int sdmbin::BaselinesSet::baselineIndex ( asdm::Tag antennaId )

Baseline number for a given antenna identifier.

This number is equal to i+1 where i is the antenna index in the list of antennas effectively producing data. In this context this is the 'zero-baseline' number. This number never exceed the number of effectively used antennas (given by the method getNumEffAntennas()).

Parameters

antennaId Antenna identifier

Exceptions

antennaId does not correspond to any of the antenna effectively producing data.

Returns: The baseline number (one-based)

Exceptions

Error if there is no antenna effectively producing data with this antennaId.

Referenced by transferId().

unsigned int sdmbin::BaselinesSet::baselineIndex	(	asdm::Tag	antennaId1,
		asdm::Tag	antennaId2
	)

Baseline number for a given pair of antenna identifiers.

Parameters

antennaId1 Antenna identifier of one of the antenna in a pair of a non-zero baseline

Exceptions

antennaId1 does not correspond to any of the antenna effectively producing data.

Parameters

antennaId2 Antenna identifier of the other antenna in a pair to define the non-zero baseline

Exceptions

antennaId2 does not correspond to any of the antenna effectively producing data.

Returns: The baseline number (one-based)

Exceptions

Error if antennaId1 or (and) antennaId2 is (are) not associated to an antenna producing effectively data.

Note: Order of the baselines:
Example 1: Consider an antenna array with the list of identifiers (1,2,3,5) the pairs of identifier defining the baselines are in the order (1,2 1,3 2,3 1,5 2,5 3,5). Hence, if antennaId1=2 and antennaId2=3 the returned value is 3.
Example 2: Consider an antenna array with the list of identifiers (5,2,3,1) the pairs of identifier defining the baselines are in the order (5,2 5,3 2,3 5,1 2,1 3,1). If antennaId1=2 and antennaId2=3 the returned value is 3. If antennaId1=5 and antennaId2=1 the returned value is 4. Note that if antennaId1=1 and antennaId2=5 the returned value will be again 4 due to the convention that baselines are defined on the basis of a pair onf indices (see the note in the documentation for the transferId(int, int, int, int, int) method.

unsigned int sdmbin::BaselinesSet::baselineIndex	(	unsigned int	na1,
		unsigned int	na2
	)

inline

Baseline number for a given pair of antenna indices in the list of antennas effectively producing data.

Parameters

na1	index (zero-based) of antenna 1

Exceptions

na1	exceeds the maximum limit imposed by the number of antennas effectively producing data

Parameters

na2	index (zero-based) of antenna 2

Exceptions

na2	exceeds the maximum limit imposed by the number of antennas effectively producing data

Returns: the corresponding baseline number (one-based)

Exceptions

Error this methods returns 0 in lax mode if na1 or na2 exceeds this maximum limit

Note

Order of the baselines:
Example for an antenna array consisting of 4 antennas the indices describing this array range from 0 to 3. The pairs of indices for the baselines are in the order (0,1 0,2 1,2 0,3 1,3 2,3). Hence, if na1=1 and na2=3 the returned value is 5.
By definition the first index in any pair being always smaller than the second index, would in the input na1>na2, the method swaps these indices.

unsigned int sdmbin::BaselinesSet::feedIndex	(	asdm::Tag	antennaId,
		int	feedId
	)

Accessor to the feed index of a feed identifier given an antenna identifier.

Parameters

antennaId	Antenna identifier of an antenna
feedId	Feed identifier

Returns: The feed index (zero-based)

Exceptions

Error

No antenna with this antenna identifier. In this case, in lax mode, this method return -1.
No feed with this feed identifier given the antenna identifier. In this case, in lax mode, this method return -2.

asdm::Tag sdmbin::BaselinesSet::getEffAntennaId ( unsigned int na )

Antenna identifier from its index in the sequence of antenna restricted to those effectively producing data.

Parameters

na	The antenna index in the list of $N'_{ant}$ antennas effectively producing data

Exceptions

na	exceeds $N'_{ant}-1$

Returns: The antenna identifier

int sdmbin::BaselinesSet::getFeedId	(	unsigned int	na,
		unsigned int	nfe
	)

Accessor to the feed identifier given a feed index and an antenna index.

Parameters

na	The antenna index in the list of $N'_{ant}$ antennas effectively producing data

Exceptions

na	exceeds $N'_{ant}-1$

Parameters

nfe	The feed index

Exceptions

nfe	exceeds the upper limit considering the number of feeds used in the configuration.

Returns: a feed identifier

Note: In general for telescopes with no focal plane arrays (FPA), this identifier should have always the value 0. Although ALMA does not have FPAs, a feed identifier may also have the value 1. That would happen in datasets with spectral windows located in the overlap region of two receiver bands, e.g. the ALMA bands 2 and 3, some of the data obtained with band 2 and the other data with band 3 for identical spectral windows.

unsigned int sdmbin::BaselinesSet::getNumAntennas ( )

Number of antenna involved in the data if none would have been dropped.

Returns: this number $N_{ant}$ which is also the number of antenna scheduled for the observations

unsigned int sdmbin::BaselinesSet::getNumBaselines ( )

Get the number of antenna pairs if all the antennas in v_AntennaIdArray_ were used.

Returns: The number of baselines actually scheduled for the observations.

Note: This is simply given by $N_{bl}=N_{ant}(N_{ant}-1)/2$

unsigned int sdmbin::BaselinesSet::getNumEffAntennas ( )

Number of antenna actualy involved in the data.

Returns: the actual number $N'_{ant}$ producing data

Note: The constraint is that this number can not exceed the number of antenna scheduled for the observations: $N'_{ant} \le N_{ant}$ .
This number $N'_{ant}$ is equal to the number of items in the vector antennaUsedArray which have the value "true", this vector being a parameter required by the constructors.

See the BaselineFlagsMetadata class for details to define or find when a given antenna produce or not data.

unsigned int sdmbin::BaselinesSet::getNumEffBaselines ( )

Get the effective number of antenna pairs producing data.

Returns: The number of antenna actually producing data

Note: This is simply given by $N'_{bl}=N'_{ant}(N'_{ant}-1)/2$
where N'_{ant} is the value returned by the method getNumEffAntennas().

unsigned int sdmbin::BaselinesSet::getNumPDTvalue	(	Enum< DataContentMod::DataContent >	e_dc,
		EnumSet< AxisNameMod::AxisName >	es_an,
		bool	effective
	)

Get the number of primitive data values (i.e.

when a complex number counts for two values) for a block of data.

Parameters

e_dc	the nature of the data content
es_an	the sequence of axes associated to the structure for this block of data
effective	a boolean to tell if one consider only the antennas which actualy produce data or all those scheduled to do the observations.

Note: Note that ALMA has dropped this concept of restricting to the antennas that have effectively produced data. Hence in that context "effective" must be set to false and the data involving the antennas with problem will be considered as blanked on the basis of the FLAGS information.

unsigned int sdmbin::BaselinesSet::transferId	(	unsigned int	na,
		unsigned int	ndd,
		unsigned int	nbin
	)

Transfer identifier for a given node in the tree hierarchy for auto-correlation data Transfer identifier for a given node in the tree hierarchy for auto-correlation data.

Precondition: WARNING: if the use-case is CROSS_AND_AUTO and the current index ndd corresponds to the case when crossDataDescriptionId is not associated to an autoDataDescriptionId, i.e. when v_pairDataDescriptionId[ndd]==false, it is an error to invoke this method. This situation is met with DSB front-ends, the sideband separation being possible only for the cross data.

Parameters

na	Index of the antenna
ndd	Index of the dataDescription
nbin	Index for the step in a switchCycle (nbin=0 if no switchCycle mode used)

Returns: A position (counted in number of PDT values) in the container of auto-correlation data where the data starts for the selection

Note: Note that the APC axis has a size of 1 for the auto-correlations, even when, in the CROSS_AND_AUTO mode, the cross data are stored with an APC axis size of 2. Would TelCal not like this feature will have to be modified in the method size() of the base class DataDescriptionsSet and this will have an additional napc input parameter.

unsigned int sdmbin::BaselinesSet::transferId	(	unsigned int	na,
		unsigned int	nfe,
		unsigned int	ndd,
		unsigned int	nbin
	)

Precondition: WARNING: if the use-case is CROSS_AND_AUTO and the current index ndd corresponds to the case when crossDataDescriptionId is not associated to a autoDataDescriptionId, i.e. when v_pairDataDescriptionId[ndd]==false, it is an error to invoke this method. This situation is met with DSB front-ends, the sideband separation being possible only for the cross data.

na	Index of the antenna
nfe	Index of the feed (required when using FPAs)
ndd	Index of the dataDescription
nbin	Index for the step in a switchCycle (nbin=0 if no switchCycle mode used)
