Pickles is a Macintosh program that was first developed by the HST Astrometry Team as a tool for determining pointings and rolls of the Hubble Space Telescope when desired target and guide stars were in the fine guidance sensor "pickles". Over time, it has become a much more sophisticated tool, and now includes apertures for all the Hubble science instruments, the ability to add user-defined apertures and the ability to display an 8! x 8 degree (HST Fixed Head Star Tracker) window. It has the new aperture locations from the post-servicing mission telescope. Because of its ability to extract and display star positions from the Guide Star Catalog, ACRS, SAO, AGK3 catalog CD ROMs, pickles is also being used in other astronomical projects. Pickles is a powerful, easy-to-use tool for visualization of star positions for any purpose.
