Frequency estimation may be wrong (re: cvel CASA bug) #13

Closed ryanaloomis closed 9 years ago

ryanaloomis commented 9 years ago

Currently frequencies are calculated using the MS header info. This header info is wrong after cvel is applied to a MS, due to a CASA bug (to be fixed in 4.5).

The frequencies should be pulled from the SPECTRAL_WINDOW table in the MS instead.

Fixed with commit aa1c3dfc2be233035a1ff4f7ae3fc8a083998bb7, using msmetadata instead of SPECTRAL_WINDOW table
