Plotmosaic

Return to Analysis Utilities

This page documents the plotmosaic function of Python module analysisUtils.

This function produces a plot of the pointings in a MS with primary beam FWHM circles and field names overlaid. For a multi-source file, you can include the sourceid to limit the fields to the science target. The default coordinate system is 'relative'. You can also use 'absolute', in which case the RA and Dec are shown in decimal degrees. This could be improved to be HH:MM:SS if there is demand. (Note: plotmosaic and plotMosaic are synonyms.)

Usage:

au.plotmosaic(vis, sourceid=2, figfile='mosaic.png', coord='relative', skipsource=-1, doplot=True, help=False)
Notes: sourceid can be either an integer or the source name in quotes. figfile can be either a string or "True".

Examples

# In CASA
au.plotmosaic('Antcont_Northall.ms',figfile=True)

Mean frequency = 344.908330 GHz
Found 23 pointings
Wrote file = Antcont_Northall.ms.pointings.png

# In CASA
au.plotmosaic('Antcont_Northall.ms', sourceid=0, figfile=True)

Mean frequency = 344.908330 GHz
Found 23 pointings
Wrote file = Antcont_Northall.ms.pointings.png

# In CASA
au.plotmosaic('Antcont_Northall.ms', sourceid=0, figfile=True, coord='absolute')

Mean frequency = 344.908330 GHz
Found 23 pointings
Wrote file = Antcont_Northall.ms.pointings.png
