Note on FITS Header

The FITS key CALSTAT will be updated after an image is successfully calibrated.  Four different letters may appear in this key.  'B' appears to indicate that the image was bias-corrected, 'D' to indicate that a dark frame was applied, and 'F' indicates that a flat field was used.  The letter 'M' may also appear if a master frame has been generated. 

Both monochrome and color images may be calibrated. Subframe images, of either type, may be calibrated using groups of full-frame calibration images.
