Use casacore to support uvfits files? #79

Closed Luke-Pratley closed 6 years ago

Luke-Pratley commented 8 years ago

Recently we have found a bug in when casa converts uvfits files to measurement sets. This bug degrades the data (I suspect the weights are converted wrong).

For this reason, we might want to support reading in of uvfits files. Casacore contains a a method to read uvfits files into measurement sets http://casacore.github.io/casacore/classcasacore_1_1MSFitsInput.html

Assuming casacore is not broken like casa, it might be worth reading a uvfits file as a measurement set object. Then we can support uvfits files with not much work.
