Return to Analysis Utilities

This page documents the plotPWV function of Python module analysisUtils.

If the ASDM_CALWVR table is present in your ms, this function will extract the PWV values from each ALMA antenna's WVR and create a plot vs. time. If the ms does not have the ASDM_CALWVR table or it is empty (as in 7m-only datasets), it will then use the ASDM_CALATMOSPHERE table. If you have neither of these tables, but you do have the ASDM, you can instead use plotPWVFromASDM

Help on function plotPWV in module analysisUtils:

# In CASA
au.plotPWV(ms, figfile='', plotrange=[0, 0, 0, 0], clip=True)
    Read and plot the PWV values from the ms via the ASDM_CALWVR table.
    Different antennas are shown in different colored points.
    Arguments:
    ms:  the measurement set
    plotrange: the ranges for the X and Y axes (default=[0,0,0,0] which is autorange)
    clip:  default=True,  True=do not plot outliers beyond 5*MAD from the median.
    figfile: True, False, or a string
             If figfile is not a string, the file created will be <ms>.pwv.png.

Examples

au.plotPWV('X3c1.ms', figfile=True)

X3c1.ms.pwv.png
