Level 2 Help for CCDRECIP

INP

The Reciprocity File created by LTGEN and MOMGEN
containing area statistics for calculating the sensitivity
and shutter-offset.


OUT

A MARK formatted data set containing rejected area locations.


SIGTOL

Specifies the number of standard deviations from the mean which
signifies a bad area.  See REJECT parameter.


REJECT

REJECT=0  No area rejection performed
      =1  Reject areas with bad sensitivity
      =2  Reject areas with bad shutter-offset
      =3  Reject areas with either bad sensitivity or offset
Areas with values differing from the mean by more than SIGTOL sigma are
rejected.


UNITS

Specifies whether the illumination values are in LUMINANC (Relative-Foot-
Lamberts ) or RADIANCE (picoamp).
(UNITS should be LUMINANC for Galileo and RADIANCE for Cassini).


LIGHT

The illumination (in Relative Foot Lamberts or picoamp)
for each exposure level of the reciprocity sequence.  The first entry should
be 0.0, corresponding to EXPO=0.0 in the reciprocity file for the Dark Current
frames.


LTFILE

Name of file containing list of illumination values in Relative Foot-Lamberts
or picoamp).  This is an ASCII text file containing one
record for each exposure level from dark-current (record 1) to the highest
exposure level (the last record).  Each record contains one floating point
value denoting the illumination value for that exposure level.


DIRECTIO

Specifies whether to derive a line-dependent or a sample-dependent shutter-
offset.  This corresponds to the direction of shutter movement (LINE or
SAMP).


ARRAYSIZ

Specifies how many elements to calculate for the output shutter-offset file.
This correspondes to the number of image pixels in the direction of shutter
movement (i.e., the number of image lines or the number of image samples).


PLOT

Specifies the name of a file to contain the plot data when the plotting
device is specified as the printer (i.e., PLOTTING 'PRINTRONX) or other
devices besides the display monitor.  For the printer, the file must be
printed using the /NOFEED qualifier.


AREATBL

The AREATBL parameter produces a tab-delimitted ASCII text file containing:
MEAN_DN(D), LUM(L), EXP(T), L*T, (T-To), D/L, D/L*T, and D/L*(T-To)
for each exposure level.


OFFTBL

The OFFTBL parameter produces a tab-delimitted ASCII text file containing:
For line-dependent shutter-offsets: Line number and calculated SHUTTER_OFFSET
for all good areas.
For sample-dependent shutter-offsets: Sample number and calculated SHUTTER_
OFFSET for all good areas.


AVOFFTBL

The AVOFFTBL parameter produces a tab-delimitted ASCII text file containing:
For line-dependent shutter-offsets: Line number and mean SHUTTER_OFFSET for
each row of grid areas.
For sample-dependent shutter-offsets: Sample number and mean SHUTTER_OFFSET for
 each column of grid areas.


CORRTBL

STRING - COUNT= 0:2 OPTIONAL
Specifies the two files two contain the uncorrected and the corrected
sensitivity values averaged by grid column or row.  The DIRECTIO parameter
specifies whether averaging is done by row or column.  If DIRECTIO is LINE,
then the values of the grid rows are averaged.  If SAMP, then the values
of the grid columns are averaged.


OFFSETS

Specifies the name of an output file that will receive the shutter-offsets for
each image line or sample from 1 to ARRAYSIZ.  The file is in standard VICAR
image format and is used as an input to programs CCDSLOPE, GALGEN, and GALSOS.
