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/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.

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. N2: V475 Sct = Nova Sct 2003. Finding chart is http://www.astro.sunysb.edu/fwalter/FC/v475sct.jpg N3: Nova Sag 2004 C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. 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. + = 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.
