This directory contains a collection of utilities for correlating LWA data with the VLA 4-band system.
Given a collection of LWA and VLA data files or a directory containing LWA/VLA data files, create a configuration file for superCorrelator.py. The configuration file is written to standard out and contains:
- the phase center,
- the file names with full path information,
- the file types,
- the antenna locations in a LWA-centric reference frame, and
- the polarizations
Simple script to plot up where all of the antennas are located in a configuration file.
Given a configuration file, correlate LWA and/or VLA according to that configuration.
There are various command line options to control the FFT window size and the
correlator dump time. The output of superCorrelator.py is a collection of .npz files,
one for integration, that contain the visibility data.
Similar to superCorrelator.py but implements pular binning using a .polyco file.
Script that takes in a collection of .npz files generated by superCorrelator.py and makes a plot of the uv coverage.
Script to generate plots of visibility amplitude and phase as a function of time and frequency.
Script to generated a VLBA sniffer-style plot for all baselines to a specified antenna.
Given a collection of .npz files generated by superCorrelator.py, perform a course fringe search to determine the antenna clock offsets. Prints out the peak delay and fringe rate determined by the search for each baseline examined.
Given a collection of .npz files generated by superCorrelator.py, convert the .npz files into one or more FITS IDI files for loading into AIPS.
Similar to buildIDI.py but useful for LWA-only observations so that both tunings can be packed into a single set of files using. Each tuning is created as a seperate IF.
Simple script to check the flow of time in a VDIF file. This can be useful for checking for missing frames/polarizations.
Simple script to check the power levels in a VDIF file.
Simple script to generate spectra for each thread in a VDIF file.
hdfWaterfall.py-style script to take in a VDIF file and build a HDF5 files containing dynamic spectra. This file can be viewed/interacted with using the plotHDF.py utility in the LSL Commissioning extension.
