F: faint companion to brighter star - check finding chart H: target is far to the north. It must be observed within +/- 20 minutes of transit to keep the zenith distance <60 degrees. M: moon within 10 degrees. Skip if the star is not seen in the acquisition TV E: may be below the east limit if you get to it early. N: Nova. Will be fainter than on finding chart. R: radial velocity standard. ST: If you cannot observe Feige 110 early in the evening, please be sure to observe mu Col (in the backup list) as the spectroscopic calibrator. TC: time critical. Please observe at the requested time. W: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end. X: same target as the previous one. Do not move the telescope. Y: 5 arcsec SE of brighter star. Skip and replace with backup target if not clearly resolved. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = absolute highest priority 1 = observe object if possible 2 = extra targets; skip if running behind and Priority 1 targets remain unobserved. 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after; 3 means before, after, and between each exposure. The T column lists the approximate time in minutes for this line. This includes 5 minutes acquisition plus 1 minute for the comparison. The CDT column is the approximate start time assumed for scheduling purposes. If you fall too far behind, you may need to drop some priority 2 or 3 targets, but otherwise don't pay too much attention to it. As I get experience with scheduling, I will try to make it more accurate. For now I am allotting the nominal overheads, plus 25 minutes for a change in the grating tilt/filter. .............................................................................. Notes about finding charts: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Most charts are available via the link from the main 1.5m scheduling page. ..............................................................................
