LOFAR Single Station Software AND More!

Last Updated: 6.07.14

This is a collection of python scripts useful for manipulating LOFAR station correlation data products and converting them to standard Measurement Sets.

Use the '-h' flag for script help

• Numpy
• PyEphem (rhodesmill.org/pyephem)
• pyrap (code.google.com/p/pyrap)
• Matplotlib/pylab w/ Basemap
• makems (Part of the MeqTrees repo)
• pywcs

Currently the package doesn't have a installation module, to use the software add this to your .bashrc file:

export PYTHONPATH=$PYTHONPATH:/home/[user]/sw/lss/src

export LSSDATA=/home/[user]/sw/lss/data

Example LBA and HBA correlation files is available at:

• LBA (RCU 3): https://zenodo.org/record/840405/files/20120513_052251_acc_512x192x192.dat
• HBA (RCU 5): https://zenodo.org/record/840405/files/20111205_162258_acc_512x192x192.dat

Extract Subbandss from ACC files and generate Measurement Sets:

gen_sb_ms_n.py -F AntennaField.conf -A AntennaArrays.conf -r 3 -s 103,155,200,245,300,350,400,420 -t 1 20120513_052251_acc_512x192x192.dat

Add the following scripts:

• derive polarization calibration file
• derive intensity calibration file
• plot calibration file
• apply calibration files
• plot XYZ, UVW
• plot PSF
• convert XST/ACC -> MS
• plot SST file
• convert DFT image -> FITS
• convert FFT image -> FITS
• plot all sky FITS file
• convert XST/ACC files -> HDF5 container
• convert SST files -> HDF5 container

AABeamGen:

• Generate antpos without AntennaArrays files
• test with OSKAR

Installation and Setup:

• remove hard-coded paths
• make a proper python module

Documentaion:

• write plotting and calibration guide
• write OSKAR beam generator guide
