Header choke causes a ds9 pvextractor failure. #20

Closed low-sky closed 10 years ago

low-sky commented 10 years ago

The following header barfs with a 

ERROR: ValueError: No valid coordinate format found. [pvextractor.pvregions]

@low-sky - are you still seeing this issue? pvextractor should be using SpectralCube to read in the data, so it should work now.

Looks resolved to me. Nice work!
