GARTH
Name
garth
Purpose
Visual inspector of moving target triplet detections.
Description
First, some vocabulary:
Object - Putative detection of a moving source. Consists of three positions
measured from three images taken at different times.
Field - A single location in the sky that has been imaged at three
different times. Each field has a name and three files names
for the three images. Each field also has an assocated list
of objects.
Triplet List - This is a list of fields, ie., a list of field names and
the file names for the images.
To begin processing the object list(s), there must be a triplet list file.
These files end with a .match suffix. For every entry in the .match file
there must be an object list file. These are named FLDNAM.obj where FLDNAM
is the name of the field found in the first column of the .match file.
ex:
field_1 980115.001 980115.051 980115.101
field_2 980115.002 980115.052 980115.102
could be two list from a .match file, perhaps named 980115.match. There
would then be two related files, field_1.obj and field_2.obj that would
have the object list. The object list files are created by the program
LINKOBJ and are not intended to be directly edited (though with care, this
is possible).

Inputs
Optional Input Parameters
Keyword Input Parameters
KEYLIST= : Name of a file containing a correspondence list. This list
associates a set of standard names with the actual keyword
names found in a FITS file header. If this keyword is
omitted, a default list is used, as if a file with the
following contents had been supplied:
AIRMASS K AIRMASS
DATE K DATE-OBS
DATETMPL T DD-MM-YYYY
EXPDELTA V 0.0
EXPTIME K EXPTIME
FILTER K FILTERS
FILENAME K CCDFNAME
OBJECT K OBJECT
UT K UT
The middle column is a flag. It may be K, for Keyword,
T, for Template, or V, for Value. If it is V, the contents
of the third field on that line should make sense for the
name in the first field.
PATH - Optional path for original image directory.
If not specified, the current directory is used.
SUBSIZE - Size of the sub-images to show (default = 249 pixels)
