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 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. F: Faint supernova may be difficult to see with moon up. Use offset coordinates, and complete full integration. G: galaxy. Center on nucleus. N: fading nova nN: New nova. see CBET 121, 123, and 124. Finding chart is http://www.astro.sunysb.edu/fwalter/SMARTS/FC_N_Norma_2005.gif. The chart is a 5x5 arcmin portion of the DSS with N up and E to the left. The nova should be in the center and quite bright. nD: new dwarf nova. See IAUC 8495 and CBET 120. Finding chart is http://www.astro.sunysb.edu/fwalter/SMARTS/FC_pyx_dn.gif The chart is a 5x5 arcmin portion of the DSS with N up and E to the left. The target should be the brightest star near the center, and may be the NW component of the close pair just below the center. 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. Charts for many objects should be available at the telescope.
