bimacalibrater.setdata - Function

	Package	bima
	Module	bimacalibrater
	Tool	bimacalibrater

Set the data parameters selection for subsequent processing

Synopsis
setdata(sources, mode, nchan, start, step, mstart, mstep, uvrange, sourcenames, msselect)

Description
This function is a wrapper around the calibrater tool's sedata function. The difference being that multiple sources can be specified, although the specified data selection will be the same for all of them. The sources parameter takes a list of source nicknames and/or a list of roles (acceptable roles are 'all','targets','phcals','pbcals','fcals'; see getsourcenames for details). The sourcenames parameter allows selection of sources in multisource datasets. These names are read from the SOURCE subtable of the Measurement Set and the appropriate FIELD_ID selection is appended to the msselect string.

Arguments

sources		Nicknames of sources on which to run calibrater.setdata()
		Allowed:	Vector of strings (nicknames or roles of sources)
		Default:	'phcals'
mode		Type of processing: channel or velocity
		Allowed:	'channel'|'velocity'
nchan		Number of channels to select
		Allowed:	Int
		Default:	1
start		Start channel (1-relative)
		Allowed:	Int
step		Step in channel number
		Allowed:	Int
mstart		Start velocity (e.g. '20Km/s')
		Allowed:	Quantity
mstep		Step in velocity (e.g. '100m/s'
		Allowed:	Quantity
uvrange		UV range (in klambda) (e.g. [0, 50])
		Allowed:	Vector of Doubles
		Default:	0 (all data)
sourcenames		List of sources to select (only useful for multisource datasets; see above
		Allowed:	Vector of strings
		Default:	' '
msselect		TAQL selection string
		Allowed:	String

Returns
T or fail

Example

- bc := bimacalibrater(['sgrb2.ms','sgra.ms'],
+ '1733-130.ms',targetnames=['sgrb','sgra'],phcalnames='1733'); 
- bc.setjy(fluxdensity=[5,0,0,0]);
T
- bc.setdata('1733',mode='channel',uvrange=[10,50]);
T
