	Tool	iramcalibrater

perform amplitude calibration on the data

Synopsis
amp(fieldnames, freqgrp)

Description
This function performs a phase calibration using the selected calibration sources and spectral window ids. Previously bandpass, phase and flux calibrated data are averaged in the spectral domain, are used to find the amplitude solution. The solutions are antenna based cubic splines. A plot of the solution is returned to the disk as a postscript file with a name consistent with the ms file.

Returns
Bool

Arguments

fieldnames		Field names of calibrators to be used
		Allowed:	Vector of Strings
freqgrp		frequency group to use
		Allowed:	'3mm-LSB' || '3mm-USB' || '1mm' || '1mm-LSB' || '1mm-USB'
		Default:	'3mm-LSB'

Example

myic:=iramcalibrater('mynew.ms')      
myic.phcor(F);
myic.rf(fieldname='0528+134', freqgrp='3mm-LSB')
myic.phase(fieldnames=['0528+134', '0415+379'], freqgrp='3mm-LSB')
myic.flux(fieldnames=['0528+134', '0415+379', 'MWC349'], freqgrp='3mm-LSB', plot=T)
myic.amp(fieldnames=['0528+134', '0415+379'], freqgrp='3mm-LSB')
myic.done()

In the example above we used 0528+134 to do the bandpass calibration and fields 0528+134 and 0415+379 to do the phase and amplitude calibration, while using '0528+134', '0415+379', 'MWC349' for flux.
