Get a list of polarization ids

Synopsis
polarids(stokes)

Description
Get a 1-based vector of integers representing the polarization ids (row numbers) from the POLARIZATION subtable by specifying a stokes parameter. If no such polarization exists in the subtable, an empty vector is returned.

Arguments

stokes		The stokes parameter associated with the polarization id (e.g., 'YY', 'I')
		Allowed:	String

Returns
Vector of integers: the corresponding polarization ids or an empty vector if the specified polarization is not found

Example

# construct a bimams tool and assign it to a Glish variable named bms
bms := bimams('neptune.ms');
# get the polarization id associated with the YY stokes parameter
bimams.polarid('YY');

The last command will return the corresponding row in the POLARIZATION subtable, for example 1
