mksarray: MeerKAT Subarrays

Simple display tools for easy viewing of MeerKAT array or any selected subarrays

Views of MeerKAT array

Simple quick layout
mksarray --enu ../config/mkat_antennas.enu --layout
Antenna locations on EARTH grid using astropy coordinates
mksarray --enu ../config/mkat_antennas.enu --map

Standard pre-defined subarrays

Display a list of all pre-defined subarrays
mksarray ../config/mkat_antennas.enu --enu --sub ?

Known subarray configurations:
	ar1, ar2, mkatcore, mkat

Display a known layout

Default behaviour will be to display the selected subarray. When adding the -o option the graph will be saved to a standard output image, SubArrayLayout.png. Add the -v option to both display and create output file as shown:
mksarray ../config/mkat_antennas.enu --enu --sub ar1 -v -o

User defined antenna selection

Selection of a list of antennas
mksarray --enu ../config/mkat_antennas.enu --ant 'm001,m006,m010,m014,m021,m025,m031,m034'

Output of .itrf file for use in PSF simulator
mksarray --enu ../config/mkat_antennas.enu --ant 'm001,m006,m010,m014,m021,m025,m031,m034' -s
