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, field=, dropTPpads=False)

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.

field: if specified, then report the date/time of the first observation of this field (ID or name), e.g. for usage in predictcomp

dropTPpads: if set to True, will exclude pads starting with 'T70', as their files do not have the same coordinate system as the others.

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).
