Return to Analysis Utilities

This page documents the gjincBeam function of the Python module analysisUtils.

This function calls the gjinc class to compute the effective restoring beam obtained from the casa command sd_imaging when using the GJINC gridding kernel assuming the GJINC specific parameters are left at their default values. It returns the value in arc seconds.


Usage

au.gjincBeam(frequency, pixelsize=10, diameter=12.0, samplingFactor=2.5)

   frequency: floating point number in GHz (no units)
   pixelsize: floating point number in arcseconds (no units)
   diameter: the diameter of the single dish antenna in meters (no units)
   samplingFactor: the number of sampled points per telescope FWHM 

Example

# In CASA
import analysisUtils as au
au.gjincBeam(115.27)
