where M and C are the measured and corrected intensities (after bias subtraction) respectively. John Barton's memo gives a value of alpha=3.16E-6, and this is the reset value.
C C D L I N Applies a linearity correction to data from the AAO RCA CCD. The correction applied is that given by John Barton (RCA#5 Non-Linearity Correction, AAO Internal Document). Command parameters - IMAGE (Character) The name of the structure containing the image. ALPHA (Numeric) The value of the constant alpha in the expression giving the linearity correction. CBIAS (Numeric) The value of the bias level to be applied when making the correction. This is not a particularly critical parameter. OUTPUT (Character) The name of the result of the operation. This can be the same as for IMAGE. If not, a new structure is created, with everything but the data a direct copy of the input. KS / AAO 10th Sept 1986
