rpds pds_file file_list iraf_file
pds_file
The PDS data source. The data 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.
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.
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.
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.
long_header = no
If this switch is set the full PDS header is printed on the standard output.
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.
datatype = s
The IRAF image data type, s (short integer), i (integer), l (long integer),
r (real) or d (double).
tenbit = no
Old ten bit format?
ninetrack = yes
Ninetrack or old seven track tapes?
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".
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.
Convert a ninetrack PDS image tape to a set of IRAF images.
cl> pdsread mtb1600 1-999 images
List the contents of a nintrack PDS tape on the standard output.
cl> pdsread mtb1600 1-999 images ma-
Convert a list of pds file on disk to IRAF images.
cl> pdsread pds* 1 images
