listazel
Return to directory of Todd's CASA extensions
Extracts the mean azimuth and elevation for the specified 'scan' in the
specified ms. This function uses msmd (or
ValueMapping if casa < 4.1.0).
Usage:
au.listazel(vis, scan=None, antenna='0', vm=0)
Inputs:
- vis: measurement set
- scan: can be a single scan or a list, as in [1,2,3], or in '1,2,3'. If not specified, then it uses all scans and computes a time-based average. If a list is specified, then it computes a scan-based average, so scans of different durations count equally.
- antenna: either the antenna number or its name.
Examples:
CASA <4>: au.listazel('uid___A002_X837c61_X573.ms',1)
Scan 1 (field=[0]): azim = 87.36, elev = 41.31 (degrees)
Out[4]: [87.361383589690448, 41.310493401884415]
CASA <2>: au.listazel('uid___A002_X837c61_X573.ms',[1,2],antenna='DA41')
Scan 1,2 (field=0): azim = 87.25, elev = 41.56 (degrees)
Out[2]: [87.246279942736081, 41.556433274098161]
