SKYMAP Example 5: Batch Search from Catalog

The easiest way to use skymap to plot finder charts for a series of objects is to put the object positions in a catalog and plot from that catalog. That way you don't have to worry about mistyping, and the source of the position will be in the heading. It is also possible to list the positions of the plotted Guide Stars (or stars from any other displayed catalog) in a separate file.

Here is the output map, with the center marked by an open cross. If the star was in the Guide Star Catalog, it would be visible in the center of the cross-hairs. To see the Postscript output, click on this map.

Here is a subset of a catalog of stars, stored in file, which were possibly occulted by Pluto in the SAO TDC ASCII catalog format.

After setting up the field size and the star catalogs to be plotted using skymap in its interactive mode as in Example 4, a shell script can be used to center maps on every star in the catalog. In the first skymap call, a is set to the initial value of 1, and b to one value past the final desired star. Within the loop, skymap is executed, producing a map of which a hard copy is made by pstek. 1 is added to cstar, and a is set to the new value of cstar. The loop continues until a is equal to b, that is until cstar is increased to 10.
skymap menu=n sfname="" sfdir="/home/mink/Stars/occult" stop
b=`skymap parval=y cstar=10 cstar`
a=`skymap parval=y cstar=1 cstar`
while test "$a" != "$b"
    pstek skymap.plot
    echo hardcopy for star `skymap cstar` in queue `date`
    skymap cstar+1 stop
    a=`skymap cstar`
skymap menu=y stop
