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.

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 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.

Parameters:

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)

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.

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

Parameters:

na1	Index of the antenna 1
na2	Index of the antenna 2
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 cross-correlation data where the data starts for the selection

Note:: A baseline corresponds to a pair of indices. The convention is that the first index is smaller than the second one (i.e. na1<na2). In case na2<na1, this method will consider na2 as the first index and na1 as the second one.

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

Parameters:

na1	Index of the antenna 1
na2	Index of the antenna 2
nfe	Index of the feed (required when using FPAs)
ndd	Index of the dataDescription
nbin	Index for the step in a switchCycle (0nbin=0 if no switchCycle mode used)

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

Note:: A baseline corresponds to a pair of indices. The convention is that the first index is smaller than the second one (i.e. na1<na2). In case na2<na1, this method will consider na2 as the first index and na1 as the second one.
