Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: M: moon within 10 deg. Skip if you do not see the star in the acquisition TV M*: moon within 5 deg. Skip if you do not see the star 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. C: cataclysmic variable: may be fainter than on finding chart. If any emission lines are overexposed in the first spectrum, shorten the exposure time and take 3 more. G: galaxy. Center on nucleus. N: fading nova PM: may have significant proper motion S1: set slit width to 2.0 arcsec. observing sequence is: comparison lamp 1 observation centered on target 1 observation centered 30" East of target 1 observation centered 30" West of target remember to reset the slit width following observation. S2: set slit width to 10.0 arcsec use same observing sequence as in note S1. remember to reset the slit width following observation. -------------------------------------------------------------------- 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 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 local 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. For now I am allotting the nominal overheads, plus 20-25 minutes for changes in the grating tilt/filter. .............................................................................. 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.
