An image from the light transfer sequence. The image label is used to identify the output Light Transfer File.
The output Light Transfer File (LTF). For details use HELP MOMGEN and TUTOR MOMGEN.
INTEGER-OPTIONAL AREA=(SL1,SS1,NL1,NS1,SL2,SS2,NL2,NS2,...,SLn,SSn,NLn,NSn) specifying the size fields of up to 125 areas in the image.
KEYWORD-OPTIONAL Generates a 10x10 grid of areas uniformly distributed over the image to be used to produce the statistics in MOMGEN. Each area will be 20x20 in size. The resolution of this grid can be increased by using the GRES keyword.
INTEGER-OPTIONAL GRES=(N,NL,NS) Generates an NxN grid of areas uniformly distributed over the input image. The areas are NLxNS pixels in size. Data is extracted from these areas by MOMGEN and stored in the LTF. Maximum N is 20. Default GRES=(10,20,20).
REAL - (Required if LIST is not used)
A string of floating point numbers specifying the commanded exposure times
(in msec) of the light transfer sequence in ascending order.
The first exposure is usually the dark current (0.0 msec):
EXPO=(0.0,4.167,6.25,8.33,12.5,16.67)
Galileo specific:
If extended exposure frames are present in the sequence, then
the sequence should begin with the extended-exposure dark-current
(specified as -1.0 msec), followed by the normal DC, followed by the
rest of the exposure levels:
EXPO=(-1.0,0.0,4.167,6.25,8.33,12.5,16.67)
However, sequences which consist entirely of extended-exposure mode
frames should be treated as though they were normal exposure frames
I.e., the extended-exposure dark-current should be specified as
0.0 exposure, and later, when running CCDNOISE or CCDSLOPE, the EXTEXPO
parameter should not be used.
INTEGER - (Required if LIST is not used) Specifies the maximum number of frames at any one exposure level of the light transfer sequence.
STRING - Optional Specifies the name of a SRCH-format ASCII file containing a list of the filenames of all frames to be processed by MOMGEN. The list must be in order of increasing exposure time. LTGEN will automatically extract the exposure times from the VICAR labels and determine the proper value of NI. This probably should not be used for the special case of extended-exposures for Galileo.
KEYWORD Invokes special debug print.
