BUG:	If the calculation datatype is set to short, calculation of the
	CCDMEAN value is incorrect and, if used during flat fielding, will
	give incorrect scaling for the flat fielding.  The workarounds are
	to not use short for the calculation datatype though it is ok to
	use short output datatype to save diskspace.  Note that if no
	calculation datatype is specified it defaults to real so it takes
	an explicit setting of pixeltype='short short' or 'real short' to
	force this bug to appear.

STATUS:	Fixed after V2.10.3.
