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 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 three spectra, each with between 5,000 and 30,000 counts per pixel.

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 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. **: may have significant proper motion. -------------------------------------------------------------------- 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 .............................................................................. 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. STSI 03b-02: Most of the stars have large proper motions, so charts may be necessary to find them. A complete set of charts has been posted at http://www.stsci.edu/~bond/valenti_finding_charts.pdf , which you should download and print out (12 MB pdf file). The charts mark where the stars will be in 2003. Some of the stars are binaries, and the remarks give the separations. If both components are listed, try to obtain separate spectra of each component. STSI 03b-03: The finding charts are in two binders at the telescope. SUNY 03b-01: Finding charts are available at http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/suny03b-01.tar.gz SUNY 03b-02: Finding charts are available at http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/suny03b-02.tar.gz CHIL 03b-01: Charts are at http://www.stsci.edu/~bond/Ogle005312.jpg and http://www.stsci.edu/~bond/Ogle051553.jpg , but Dr. Mennickent has been asked to send you better ones. YALE 03b-08: These are galaxies, but they may look almost stellar. ..............................................................................
