New notes: Based on performance earlier this semester, I am assuming that observations can start about 30 minutes before the end of astronomical twilight. 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. If you start late, pick up the timeline with the first priority 1 target observable. .............................................................................. In afternoon or during dinner: - Install 26/I grating setup - obtain at least 10 Zero frames - obtain at least 5, preferably 10, flat-field frames (projector or dome) Get well-exposed twilight spectrum at zenith at beginning (or end) of night. Aim for 3 spectra, with 5000-30000 counts/pixel. Do not overexpose the long wavelength end of the chip. ..............................................................................

Aim for 3 spectra, with 5000-30000 counts/pixel. Do not overexpose the long wavelength end of the chip. .............................................................................. Remarks: **: Nova Crux is an important and time-critical target. It is, however, 5 hours west 20 minutes before the end of astronomical twilight. Please make every effort to start early. I'm assuming you can start about 40 minutes before the end of twilight, or about 1908 CST. If you cannot start before 1930 CST, skip this target. If any part of the spectrum is saturated, repeat with 60 second exposures. 1: moon within 10 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. 2*: If HU Aqr is visible, however faint, do a full set of 3 integrations. 3: Far northern target. Hour angle must be less than ~2h. 4: consider only if there is at least an hour left before twilight. 7: variable star. If any emission lines are saturated, please repeat observation with shorter exposure times. .............................................................................. General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = Time critical or TOO target. Highest 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. 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 SUNY 03b-11: Finding chart for Nova Sct 2003 ia available at http://www.astro.sunysb.edu/fwalter/SMARTS/2003B/nova_sct.gif 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. ..............................................................................
