MeerKAT and EVLA S band coeffs from avg beams
Added new Zernike coeffs for MeerKAT and EVLA S band created from the array
averaged beams after the pointing errors have been taken out.
Added new coefficients for MeerKAT
These new coefficients have been derived from updated holography averaged over
all antennas. The holography measurements were obtained from
Mattieu De Villiers at SARAO.
Small bugfix for coeff txt files.
If the # was missing from the first line of the csv files, it results
in undefined behaviour because the code tried to convert a str to an
int. It would sometimes work but usually not. That's now been fixed.
Added S band coeffs, modified L band coeffs
Currently switching between S band and L band by changing the filename
in the code - but eventually all the coeffs will live in the same csv
file.
These S Band coeffs are identically zero for SPW2 since the data was
particularly bad.
