BuildConfigurationFile

Return to Analysis Utilities

This page documents the buildConfigurationFile function of Python module analysisUtils.

This function will read the list of antenna stations in an .ms and creates a .cfg file based on the antenna locations in the files in /usr/lib64/casapy/data/alma/simmos (Linux path). It is useful for preparing to run simulations to mimic the uv coverage of previously-obtained datasets.

Usage:

au.buildConfigurationFile(vis=", simmospath=None)

If the path to simmos is not found, or if you have alternate .cfg files to use, then you can pass the path as a string using the simmospath parameter.

VLA example

CASA <2>: au.buildConfigurationFile('spw0_1.ms')

ALMA example

At present, only files for the official ALMA Cycle 0 and Cycle 1 configurations are available in casa, and so in some cases. pads used in Early Science observations will not be found. If you encounter this problem, then please submit a helpdesk ticket to obtain the information. Or you can consult the pad position spreadsheet yourself at this wikipage (look for Local Tangent Plane coordinates).
