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 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 0557 local time, so if all goes well this is as far as you are likely to get. If you skip targets and need more, select from the following: YALE 03b-08 2 CTS 230 03 10 02.0 -37 23 38 17.7 3x1200 1 66 4 STSI 03b-10 2 o Psc 01 45 23.6 +09 09 28 4.2 3x 10 1 7 STSI 03b-02 2 CC Eri 02 34 22.6 -43 47 47 8.9 3x200 1 16 STSI 03b-10 2 HR 856 02 53 11.7 +16 29 00 6.3 3x 10 1 7 STSI 03b-10 2 kappa Cet 03 19 21.7 +03 22 13 4.8 3x 10 1 7 STSI 03b-10 2 epsilon Eri 03 32 55.8 -09 27 30 3.7 3x 8 1 7 STSI 03b-02 2 40 Eri C 04 15 18.5 -07 39 07 11.2 3x300 1 21 STSI 03b-04 3 NGC 246 00 47 03.4 -11 52 19 11.8 3x500 1 31 Shortly before sunrise, get well-exposed twilight spectrum at zenith, if you were unable to get them at dusk. 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, increase exposure times to 3x600. 4: consider only if there is at least an hour left before twilight. .............................................................................. 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. 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. 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. ..............................................................................
