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 UT 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/II grating setup - check focus if necessary - obtain at least 10 Zero frames - obtain at least 5, preferably 10, flat-field frames (projector or dome) Get well-exposed TWILIGHT SPECTRA at zenith at beginning of night. Aim for 3 spectra, each with between 5,000 and 30,000 counts per pixel. ..............................................................................

Skip if you do not see the star in the acquisition TV 2: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. If visible but much fainter than on chart, increase exposure times to 3x600. 3: 5 arcsec SE of brighter star. 4: not observable before about 0530 local time. .............................................................................. 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 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 were prepared at telescope in February and should be available. SUNY 03b-02: Finding charts are available at http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/suny03b-02.tar.gz The finding chart for RXJ0513 is in http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/rxj0513.ps ..............................................................................
