25 July 2000 Parallel Observation Matching System for crafting overlaid science for the Hubble Space Telescope

Once primary science observations have been placed on the timeline for the Hubble Space Telescope (HST) we schedule additional (parallel) science observations that use the other science instruments. This is possible because the instruments use different places in the focal plane, because multiple instruments may be operated at once and because of improvements in the software that processes the science proposals. The Parallel Observation Matching System (POMS) forms the heart of these improvements. It identifies suitable places on the timeline for the parallel science and crafts science visits to fit them. The new version of POMS, which has been in use for 2 years, was designed to significantly reduce the special processing for parallel proposals. Parallel proposals are now described in a similar fashion to primary science proposals, so the standard software processing can be applied. The result is template visits with some flexible parameters. POMS considers each proposal in a prioritized sequence and uses the current operational version of the proposal transformation program (TRANS) to produce the detailed observation description. Currently the entire process takes under 1.5 hours to craft and schedule seven days worth of science parallel observations for the two active parallel instruments. The addition of new parallel proposals for future instruments is now a simple procedure.
