LSL - The LWA Software Library

General

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

• describe the setup (location, stand positions, etc.) of the first LWA station (LWA1),
• read in the three main data formats described in the DP ICD,
• export time series and spectral data to FITS files,
• estimate uv-plane coverage,
• simulate visibility data sets, and
• other tasks.

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.
