mocsearch - search for a select set of PDS MOC images by range contraints
This procedure calls 'mocsearch.pl' to search through the cumindex.tab
file that is available on the PDS MOC CDROM distribution.  The search
is contrained by the user specified ranges for latitude, longitude,
resolution, and 'L sub S'.  The 'TO' ouput file is a formatted ascii
table file that contains the list of images that fall within the
contraints.

The CDROM path name is included in the output file, allowing the
user to run 'MOCFTP.PDF' from tae to download the desired
images from the MOC image data set located on ida.wr.usgs.gov.
(Refer to the tae help for MOCFTP for further details).

Output files:  'TO' - formatted ascii table file

ParmDescription
IMGINDX
The default, $ISISMGSDATA/cumindex.tab, is supplied by
ISIS and was retrieved from the PDS CD-ROM volume
(MGSC_1234).  The information in this table file covers
image dates (1997-09-15 to 2002-07-31) and CD-ROM volumes
(MGSC_0001 to MGSC_1234).  In order to use the most recent
information supplied by PDS, the user can retrieve the
cumindex.tab off the latest distributed CR-ROM and set this
IMGINDX parameter to that file.
TO
Formatted ascii table file that contains 10 fields of
information of the files that fall within the user
defined constraints.

LATRNG
Minimum Latitude, Maximum Latitude range of desired
area
LONRNG
Eastern Longitude to Western Longitude of desired
area.  Notice that eastern/western longitude is
entered (not minimum/maximum).  A longitude range
of (350,10) is an acceptable range that is
considered the same as (-10,10)
RES
Resolution range in kilometers/pixel.  The default
range of 0.0 -> 0.6 is chosen so that all MOC NA
images and MOC/WA context images will be retrieved
from a search.
LSUBS
L sub S range.  The valid range is (0,360).  This
value determines the season in the northern
hemisphere at Mars.
0 = start of Spring, 90 = start of Summer,
180 = start of Fall, 270 = start of Winter.
