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/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.

Please do this at the expense of the lower priority targets.

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 moon up. R: radial velocity stardard for STSI programs. N: Nova. Will be fainter than on finding chart. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. 2: second observation of a target. Please try to maintain spacing. Y: 5 arcsec SE of brighter star.

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. AMNH 04b-01: No finding charts supplied. Proper motions are typically 0.5-1 arcsec/year, so positions are good to better than 5 arcsec.
