uvfits key describing the number of timesteps #2
Description
Not sure if there's an official uvfits key or not, but it's quite painful discovering the number of timesteps in a uvfits file -- one more or less has to read the entire file to determine it. A key (even a non-standard one) would be very useful. I guess using this key would also assume that the layout of the uvfits is regular (i.e. one timestep has x rows/baselines before the next timestep which also has x rows, etc.).
