NAME
rpds -- Convert Kitt Peak PDS image files to IRAF image files
.ih
USAGE
rpds pds_file file_list iraf_file
.ih
PARAMETERS
.ls pds_file
The PDS data source. The data source may be a template specifying
a list of disk files, e.g. pds* or a mag tape file specification of
the form mtl*[n], e.g. "mta1600" or "mtb800[1]". The mt specifies magtape,
l specifies the drive, a,b,c etc, * specifies the density and [n]
the tape file number. If no tape file number is specified rpds reads
the tape files specified by file_list.
.le
.ls file_list
A string parameter containing the list of tape files to be processed.
File_list is only requested if no tape file number is specified in pds_file.
For example the string

	"1,2,3-5,8-6"

will convert files 1 through 8.
.le
.ls iraf_file
The IRAF file which will receive the PDS data if the make_image
switch is set. If multiple files are input from tape or disk, the tape file
number or disk sequence number will be appended to the output file name.
.le
.ls make_image = yes
If make_image is not set, the PDS image headers are listed on the standard
output and no image file is created.
.le
.ls long_header = no
If this switch is set the full PDS header is printed on the standard output.
.le
.ls short_header = yes
If this switch is set only the output filename,
the title string, and the image dimensions for each image are printed
on the standard output.
.le
.ls datatype = "s"
The IRAF image data type, s (short integer), i (integer), l (long integer),
 r (real) or d (double).
.le
.ls tenbit = no
Old ten bit format?
.le
.ls ninetrack = yes
Ninetrack or old seven track tapes?
.le
.ls offset = 0
Offset is an integer parameter which is added to the tape file number
or disk sequence number and
appended to the parameter iraf_file. For example if offset = 100,
iraf_file = "pds" and file_list = "1-3" the output file names will be
"pds101", "pds102" and "pds103" respectively, instead of "pds001", "pds002"
and "pds003".

DESCRIPTION

Kitt Peak PDS data is read into IRAF from either a
list of disk files or magnetic tape.
The PDS header may optionally be printed on the standard output as either a
full listing or a short description.
