This code gives the user more information about available PCRS
peakup catalog stars. It is intended to be used in conjunction
with Spot where the catalog stars must be chosen for observations.
The catalog itself is included in the tar file.

The IRAC instrument support team recommends avoiding stars with large position errors. Position
errors in the output are calculated with an epoch of 2009.5, so are
actually larger for the current epoch. Brighter stars are more
desirable because then the peakup integration time will be shorter,
although all brightnesses are feasible. Only catalog stars with
angular distances less than ~half a degree are shown as viable
catalog stars. The best star to choose is some combination of
position error, V_mag and angular distance. If this tool shows a
star which is not listed in Spot, and it is your choice for the
best catalog star, you can always enter it manually as a PCRS
peakup star. The catalog used here is exactly the same as that
used in Spot.
