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 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. 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. ..............................................................................

Astronomical twilight begins at 0519 local time, so if all goes well this is as far as you are likely to get.

Aim for 3 spectra, with 5000-30000 counts/pixel. Do not overexpose the long wavelength end of the chip. .............................................................................. Remarks: 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, please take only one spectrum. Note on EF Eri: There are two stars of comparable brightness. EF Eri is easternmost of the pair. If only one star is visible, it is likely NOT EF Eri, and do not take a spectrum 3: Far northern target. Hour angle must be less than ~2h. 4: consider only if there is at least an hour left before twilight. 5: radial velocity standard for V838 Mon. Must be observed if V838 Mon is observed; skip if V838 Mon is not observed. A: Nova, may have faded. Far over at sunset: observe as early as possible. B: BL Cet and UV Cet form a 1.5 arcsecond pair. If you can separate the two stars, please get spectra of each separately (both 3x600 sec). If you cannot cleanly separate the two, get a single combined spectrum. C: comment from proposer: "Target RR_09 seems to have a close companion which has about the same magnitude. Please take an spectra of each one of the stars." If you cannot see a second star, ignore RR_09B .............................................................................. 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 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. ..............................................................................
