LSL

General

lsl (LWA Software Library) is a collection of python routines for working with LWA data. It consists of routines that:

  • describe the setup (location, stand positions, etc.) of the first LWA station (LWA-1),
  • read in the three main data formation described in the DP ICD as well as S60 data,
  • export time series and spectral data to FITS files,
  • estimate uv-plane coverage, and
  • simulate visibility data sets.

The library also includes a number of demo. scripts that show how to:

  • display time integrated TBW/TBN spectra,
  • read in TBW/TBN data and save the data to FITS files,
  • obtain stand positions and cable lengths, and
  • plot the station beam for a zenith snapshot.

In addition, lsl also contains the bulk of NRL's lwa_user library. See the README file for a list of which routines are included and their locations in lsl.
