Constructor & Destructor Documentation

VLAFiller::VLAFiller	(	MeasurementSet &	output,
		VLALogicalRecord &	input,
		Double	freqTolerance = 0.0,
		Bool	autocorr = False,
		const String &	antnamescheme = "new",
		const Bool &	applyTsys = True
	)

Construct a VLAFiller object that will data from the specified input, and writes it to the supplied MeasurementSet.

We set the default tolerance for frequency to be 6 times of the channel width and also give user the ability to pass in a tolerance for frequency into vlafillerfromdisk(). The default tolerance of frequency works for dataset G192. But for dataset NGC7538, one has to give a tolerance as larger as 60 times its channel width ( 60000000Hz ). For other dataset, the user has to try out the proper tolerance.

VLAFiller::~VLAFiller

(

)

Does nothing special.

	)		[private]

static MeasurementSet VLAFiller::emptyMS	(	const Path &	tableName,
		const Bool	overwrite = False
	)		[static]

Construct an empty MeasurementSet with the supplied table name.

Throw an exception (AipsError) if the specified Table already exists unless the overwrite argument is set to True.

void VLAFiller::extendHypercubes	(	const Block< uInt > &	nPol,
		const Block< uInt > &	nChan,
		uInt	rows
	)		[private]

void VLAFiller::fill

(

Int

verbose = 1

)

fill the supplied MeasurementSet from the the supplied VLABuffer.

The number/type of messages describing the progress sent to the logger are controlled using the verbose argument. If verbose is -1 or less then no messages are sent to the logger. If verbose is zero then a summary is sent to the logger just before this function completes. If verbose is one then a message is sent for every record copied to the output MS. If verbose is two a message is sent every second record and so on.

Bool VLAFiller::fillOne

(

)

[private]

Read one record from the input and copies it to the MS if it is not filtered out.

Returns False if a record could not be read.

void VLAFiller::fixFieldDuplicates

(

MSField &

msFld

)

[private]

static MeasurementSet VLAFiller::getMS	(	const Path &	tableName,
		const Bool	overwrite = False
	)		[static]

Return an empty MeasurementSet with the supplied table name.

Creates a empty measurement set unless one with the specified name already exists and overwrite is False. Then it opens the existing measurement set for read/write access.

void VLAFiller::logChanges

(

IterationStatus &

counts

)

[private]

void VLAFiller::logCurrentRecord

(

IterationStatus &

counts

)

[private]

Send to the logger info about how the filler is going.

static MeasurementSet VLAFiller::openMS	(	const Path &	tableName,
		const Bool	readonly = False
	)		[static]

Open the MeasurementSet with the supplied name.

Throw an exception (AipsError) if the specified Table does not exist. By default the Table is opened for read/write access. The Type/SubType MUST be "Measurement Set/VLA" ie., the MS must have been created with this class. Otherwise an exception is thrown.

Int VLAFiller::polIndexer

(

Stokes::StokesTypes &

stokes

)

[private]

void VLAFiller::setFilter

(

const VLAFilterSet &

filter

)

Set the filter that will be used to restrict which input records get copied to the output MS.

void VLAFiller::setStopParams	(	String &	,
		String &
	)

Set the stop Parameters for filling.

Bool VLAFiller::stopFilling

(

VLALogicalRecord &

)

[private]

void VLAFiller::summarise

(

)

[private]

Send to the logger info about how much data is in the (sub)tables.
