The files for the SAO star search (switch -f) are ssao.00-ssao.42, provided by picoscience for use
with their Superstar program. When the -f option is used, the program searches through the proper
ra-ordered file for objects within a certain radius of the target. If the radius is too small, no stars will
be found for that object. SAO stars will not be found for STD, SAO, or BST object types. The star
coordinates are accurate to about one arcsec, and the proper motions to 1 arcsec/century.
Some examples follow:
obslist sources.cat -a 14:23:34.3 -23:12:11.02 0.23 1.12 STD 1950.0 STAR1 -s
the above star is added to the end of the list, then the list is sorted and the output
catalog sent to sources.cat, overwriting the old file.
obslist sources.cat -a -s -p -t sourceT.cat > sources.lst
the sources.cat file is read in, then the program goes into interactive "add source" mode
to allow the user to type in a number of objects, then sorts the objects, makes a file
SOURCET.CAT for use on the telescope, and prints a listing of the sources. The
listing has been redirected to the file "SOURCES.LST".
OBSLIST was written in C for a PC, but can just as easily be run on other systems, such as Sun
computers. To compile the program on a PC using Microsoft C compiler vers. 5.1, use the following
statement:
cpl /F 9000 obslist.c
On a Sun, use the following command:
cc obslist.c -lm -o obslist
The size of the arrays set in the program below can be changed to increase the number of sources
allowed using the parameter MAXSRC in the program. In the case of the PC, the stack size may also
have to be increased (the /F parameter above). For other systems, some tweaking may be necessary,
but the program uses fairly standard C, so it should not be a big problem.
