photostat - Give geometric information about the image
Read image labels that have mission data including:  SPACECRAFT_NAME,
INSTRUMENT_ID, TARGET_NAME, and SPICE information and compute image re-
solution, emission angle, incidence angle and phase angle at the input
line and sample unless none are entered, in which case the statistics
will be computed at the center of the image.  Other statistics will be
latitude and longitude range, etc.  This program may be used to simply
list geometric information about the cube or it may be used in a TAE
procedure to extract information about the cube to be used by the pro-
cedure.  The values that are returned to a procedure are listed below as
output parameters.

ADDITIONAL NOTES:

ParmDescription
FROM
Input cube file name.  If the file extension is omitted,
then ".cub" will be assumed.
BAND
The band number for which the user requests to have the
filter information reported.
LINE
The latitude and longitude of any line,samp in the cube may
be listed using the LINE and SAMP parameters.  Both LINE and
SAMP must be entered to use this option.  If this option is
used, then the photostatistics will be found for this line
and sample instead of the center line and sample.
SAMP
See LINE.
LAT
The line and sample of any lat,lon in the cube may be listed
using the LAT and LON parameters.  Both LAT and LON must be
entered to use this option.
LON
See LAT.
OUTLINE
Return the line position in cube that corresponds to the
input latitude and longitude.
OUTSAMP
Return the sample position in cube that corresponds to the
input latitude and longitude.
OUTLAT
Return the latitude that corresponds to the input line and
sample.
OUTLON
Return the longitude that corresponds to the input line and
sample.
EMA
Return the emission angle at the center of the image, or at
the line and sample entered by the user.  Emission angle
will be set to 900, if the center of the image or the user
input line and sample are not on the planet.
INC
Return the incidence angle at the center of the image, or at
the line and sample entered by the user.  Incidence angle
will be set to 900, if the center of the image or the user
input line and sample are not on the planet.
PHASE
Return the phase angle at the center of the image or at
the line and sample entered by the user.  Phase angle will
be set to 900, if the center of the image or the user input
line and sample are not on the planet.
