Detailed Description

VBGContinuumSubtractors subtract the continuum out of VisBuffGroups.

Intended use:

Public interface

Prerequisite

Etymology

VBGContinuumSubtractors subtract the continuum out of VisBuffGroups.

Synopsis

This estimates the continuum by fitting a low order polynomial in frequency for each baseline in a VisBuffGroup, and then writes those visibilities, with the continuum subtracted, to a different MS. The VisBuffers in the VisBuffGroup do not all have to have the same spw, set of baselines, or even set of correlations, but output visibilities for which the continuum cannot be estimated will be flagged.

Constructor & Destructor Documentation

casa::VBGContinuumSubtractor::VBGContinuumSubtractor	(	MeasurementSet &	outms,
		MSColumns *	msc,
		const VBRemapper &	remapper,
		const ROVisibilityIterator &	invi,
		const uInt	fitorder = `1`,
		const MS::PredefinedColumns	datacols = `MS::DATA`,
		const String &	fitspw = `"*"`,
		const String &	outspw = `"*"`
	)

Construct an object that will write to outms after subtracting a continuum estimated by fitting a polynomial of order fitorder.

It will always _write_ to DATA if datacols.nelements() == 1, and write to all 3 otherwise. Thus datacols.nelements() should be either 1 or 3. Anything else will result in an AipsError. 4 and 2 are right out, and FLOAT_DATA isn't handled by this yet.

invi is the input VisibilityIterator, only used directly here to get the sort columns and whether or not WEIGHT_SPECTRUM and/or FLAG_CATEGORY are present.

These cubes could be made local to process(), but I want to avoid repeated c'ting and d'ting.
