selectionmanager.selection

Arguments

`freqsel`	Frequency/velocity selection
	`Allowed:`	`Freqsel`
	`Default:`	`unset`
`fieldnames`	Selected field names
	`Allowed:`	`Vector of Strings`
	`Default:`	`unset`
`spwids`	Selected spectral window id.'s
	`Allowed:`	`Vector of Ints`
	`Default:`	`unset`
`uvrange`	UV range (in klambda) (e.g. [0, 50])
	`Allowed:`	`Vector of Doubles`
	`Default:`	`0`
`msselect`	General MS selection
	`Allowed:`	`String`
	`Default:`	`unset`

Returns selection data item or fail

Description

This function creates a selection data item from set of selection criteria. The individual selection criteria are combined by a logical AND to form the total selection.

Example

myfq:= freqselmanager();
freqsel1:= myfq.channel(nchan=64, start=4, step=1);
mysm:= selectionmanager();
item1:= mysm.selection(freqsel=freqsel1, fieldnames=['3C84','3C273'],
   spwids=[1,2], msselect="ANTENNA1==4");

Create a selection data item item1 representing: i) frequency channel selection of 64 channels, starting at channel 4 and stepping by 1 channel; ii) for the field names '3C273' and '3C84'; iii) for spectral window id.'s 1 and 2; and iv) for all data for which the first antenna on the baseline is antenna 4. All spectral window and antenna id.'s are 1-relative, as are all MS indices in the msselect parameter.
