Detailed Description

UV FITS to MeasurementSet filler.

Intended use:

Public interface

Prerequisite

MeasurementSet
FITS classes

Etymology

MSFitsInput handles the conversion of FITS files to MeasurementSets

Synopsis

UV FITS to MeasurementSet filler. This can handle single source fits and multi source fits as written by classic AIPS. Also copes with multiple arrays (i.e. multiple AN tables) but doesn't correct for 5 day offsets introduced by DBCON.

Constructor & Destructor Documentation

casa::MSFitsInput::MSFitsInput	(	const String &	msFile,
		const String &	fitsFile,
		const Bool	NewNameStyle = `False`
	)

This is an implementation helper class used to store 'local' data during the filling process.

Create from output and input file names. This function opens the input file, and checks the output file is writable.

casa::MSFitsInput::~MSFitsInput ( )

The destructor is fairly trivial.
