New notes: 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. .............................................................................. In afternoon or during dinner: - Install 47/Ib grating setup - check focus if necessary - obtain at least 25 Zero frames - obtain at least 10, preferably 25, flat-field frames (projector or dome) Get well-exposed TWILIGHT SPECTRA at zenith at beginning of night. Aim for three spectra, each with between 5,000 and 30,000 counts per pixel.

Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: M: moon within 10 degrees. Skip if you do not see the star in the acquisition TV M*: moon within 5 degrees. Skip if you do not see the star in the acquisition TV F: faint target may be hard to see with full moon up. R: radial velocity stardard for STSI programs. N: Nova. Will be fainter than on finding chart. NN: new nova. Should have V<11 and be obvious. See IAU Circulars 8380-8382. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. S spectrophotometric standard. If you cannot observe LTT4364, please try to observe Feige 110 before changing to 47/II. V: VSST is the star about 45 arcsec SW of S CrA PM: may have significant proper motion. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = absolute highest priority 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after .............................................................................. Notes about finding charts: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Charts for many objects should be available at the telescope.
