[fitsbits] keyword for data type

[Tom Kuiper]

Greetings group!

I'd like to have a keyword that tell me if the data in a FITS file have
been processed, or if they are raw.  Something like

DATATYPE= 'raw'
DATATYPE= 'calibrated'
DATATYPE= 'processed'

Is there anything already defined along those lines?

Regards

Tom
