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 30 minutes for a change in the grating tilt/filter. .............................................................................. In afternoon or during dinner: - Install 47/II 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 star is not visible in the acquisition TV M*: moon within 5 degrees. Skip if star is not visible in the acquisition TV F: faint target may be hard to see with full moon up. R: radial velocity standard for STSI programs. N: Nova. Will have faded considerably. Lengthen time if possible, but not at the expense of S CrA C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. 2: repeat observation. Must start at least 1 hour after start of first observation. 3: 5 arcsec SE of brighter star. **: may have significant proper motion. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target 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.
