dreamBeam

DOI

dreamBeam is a python package that implements radio astronomical measurement equations. It is based on the 3D Jones formalism introduced in:

T. D. Carozzi, G. Woan, A generalized measurement equation and van Cittert-Zernike theorem for wide-field radio astronomical interferometry, Monthly Notices of the Royal Astronomical Society, Volume 395, Issue 3, May 2009, Pages 1558–1568, (https://doi.org/10.1111/j.1365-2966.2009.14642.x)

What is this repository for?

dreamBeam let's you create generic measurement equations, i.e. multiplicative chains of Jones matrices. It also comes with some predetermined, basic beam models of real telescopes, currently:

  • LOFAR (LBA & HBA)
  • NenuFAR
  • ALMA (contact me)

How do I get set up?

  • Use setup.py script to install
  • Requires: python-casacore, numpy and AntPat

Status

dreamBeam is now fairly mature.
