D Pre-Observing Run Checklist

• Badges and car passes ready. (Note: Permanent Badges should be kept for future use and should not be turned in at the gate when your observing run is completed.)
• Target priorities set and expected observing sequence laid out, including alternative sequences in the event spacecraft constraints or high radiation forces a change of plans.
• Skymaps and beta angles checked for possible constraints. Please have the skymap and accompanying target list available during your observing run.
• Added targets (if any) approved.
• Accurate 1950 epoch coordinates for targets.
• Offset stars with accurate coordinates selected.
• Finder charts, including visual magnitudes, for target identification.
• Guide stars available? (Should be brighter than 13.5 magnitude visual.)
• Estimated exposure times computed.
• Special information ready (e.g. moving target ephemeris, special observing techniques, etc.). Please contact the Resident Astronomers prior to your visit and discuss any special requirements or techniques you may wish to use. This will allow the staff to assist you in anticipating possible problems or constraints that may arise.
• Special requests approved. (Battery discharge, remote observing, priority processing, etc.)
• RDAF time reserved, if needed.
