One picture file generated by the Viking Orbiter logging program (VOLOG). This frame should be an unprocessed byte image (i.e. No stretching, filtering or geom allowed). This can be followed by a reseau location record containing the nominal reseau locations; .VARIABLE OUT A reseau record containing the (LINE,SAMPLE) coordinates for each reseau mark. This file contains just 1 line of 824 bytes. The output has a VICAR label.
Optional output file to contain GEOMA parameters for removing the geometric distortions.
Specifies the camera serial number for the input picture. This parameter may be used to override the camera information in the Viking Orbiter label. The valid camera serial numbers are: 7=VO-1A 8=VO-2A 4=VO-1B 6=VO-2B
Causes diagnostic messages to be printed.
Causes a listing of the reseau locations to be generated.
The program will normally attempt to calculate the reseau locations to sub-pixel accuracy. This keyword suppresses interpolation of the correlation maximum.
NVER is an integer specifying the height of the search area. (must be odd) (Default =19)
NHOR is an integer specifying the width of the search area. (must be odd) (Default = 19)
NLW is an integer specifying the height of the correlation area. (must be odd) (Default = 5)
NSW is an integer specifying the width of the correlation area. (must be odd) (Default = 5)
SIGMA is a real number specifying the standard deviation constant used in the reseau shape function. (Default = 1.0)
FRAME is an integer specifying the frame number for the input picture. This parameter will override the frame number in the Viking Orbiter label.
A THRESHOLD ON CORRELATION VALUES. Default is CTHRESH=0.5.
VALID = 1:8
Default is FIT = 8.
Specitfies the type of fit to be performed. Meanings are :
IFIT ROTATE SCALE OFFSET
1 0 0 1
2 0 1 0
3 0 1 1
4 1 0 0
5 1 0 1
6 1 1 0
7 1 1 1
Default is TOLER = 4.0. Maximum allowed error in calculated location relative to the nominal location.
