Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: M: moon within 10 degrees. Skip if the star is not seen in the acquisition TV B: very bright star: best observed through clouds. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. CE: EF Eri is the faint star to the East of the brighter star. Look at the finding chart is unsure. E: may be below the east limit if you get to it early. F: faint target may be hard to see with moon up. N: Nova. Will be fainter than on finding chart. R: radial velocity standard. ST: If you cannot observe LTT 4364 early in the evening, please be sure to oberve Feige 10 (in the backup list) as the specroscopic calibrator. S4: set slit width to 4.0 arcsec. S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. TC: time critical. maintain spacing between the 3 images W: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end. X: If running 10 minutes or more ahead at this point, increase exposure lengths to 600 seconds. Y: 5 arcsec SE of brighter star. Skip 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 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. Charts for most objects should be available at the telescope. ..............................................................................
