[AstroPy] pyfits query: how to include a bit mask?

[Christopher Hanley]

Russell,

My suggestion depends upon the type of FITS file you are creating.  If 
you are dealing with FITS images, I would just add another extension to 
your FITS file containing the data quality flag values you wish to use. 
  If you are writing FITS tables you could just add another column with 
the desired bit value.
