The first argument is the name of the executable file, and the second argument is the pathname of the directory which contains the default parameter file for this program. This pathname may be up to 64 characters long. If it is omitted, newdef will print the pathname of the current default directory. If there are three arguments, the second is the name of the default directory to be replaced. If the second argument is omitted, it is assumed to be /home/mink/Defaults, which works on Center for Astrophysics Computation Facility Sparcstations and Alphas. If no arguments are given, newdef prints a brief description of how to use the program. To set the default from its initial value to /usr/local/lib, for example, you would type
newdef skymap /usr/local/libIf you later want to change the default parameter directory to /usr/local/defaults, type
newdef skymap /usr/local/lib /usr/local/defaults
ftp://cfa-ftp.harvard.edu/pub/gsc/Skymap/pstek.tar.Z.
If pstek works on your system, set the HCCOM parameter in skymap.par to the appropriate command before saving it in the default directory.
Print this file using pstek, imtek, or another program, and
measure several of the lines, both vertically and horizontally, dividing their
lengths in millimeters by the marked lengths of those lines in Tektronix
plotting units, and set the parameter MDIST in skymap.par to the average
value. After setting any other parameters to values which you think users at
your site will almost always use, the skymap.par file can be
saved in the
directory you set in skymap using newdef. If different
output formats are
used, and a plate scale is to be maintained, this file can be plotted to that
format, measurements can be redone, and MDIST can be modified in a local
version of skymap.par.
Guide Star Catalog CDROM Setup
If you intend to use the HST Guide Star Catalog, two parameters in skymap.par
need to be set to tell skymap where to find CDROMs. Use your favorite editor
to set CDNORTH and CDSOUTH to the pathnames of Volume 1 and Volume 2,
respectively. The pathnames should be surrounded by either single or double
quotes.
In SunOS 4, Sun did not support an optional extension to the
ISO-9660 CDROM standard used by the Guide Star Catalog, so it is necessary to
patch the operating system to enable skymap to read the catalog. Those
patches, with directions for their application to SunOS 4.1.1, 4.1.2, and
4.1.3 can be found in the files sunos4.1.1.patch,
sunos4.1.2.patch, and sunos4.1.3.patch in the directory:
ftp://cfa-ftp.harvard.edu/pub/gsc/CDROM
Decstation Ultrix makes all file names on the CDROMs upper case, which you can see if you ls the files on the CDROMs, but skymap automatically figures out whether or not the file names are upper case.
