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 26/I 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 not visible in the acquisition TV A: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end if it helps. B: very bright target. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. E: target far to the east at twilight. Don't go there too 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 for STSI programs. PM: may have significant proper motion. W: star very close to 2 air masses at end of observation. Don't start late. Y: 5 arcsec SE of brighter star. Try to keep the brighter star out of the slit. Skip if the seeing is really bad. Z: monitoring target. Try to maintain spacing between observations. -------------------------------------------------------------------- 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. Many charts are available via the link from the main 1.5m scheduling page. Charts for many objects should be available at the telescope. ..............................................................................
