In afternoon or during dinner: - Install 47/II grating setup - check focus if necessary If there is time: - obtain at least 25 Zero frames - obtain at least 10, preferably 25, flat-field frames (projector or dome) otherwise, do the Zero and pflat exposures at the end of the night. Then switch to the echelle. The echelle is scheduled every night in August until LST = 19h. Tonight the echelle is scheduled until 2236 local time. At 2236 CST, switch to the RC spectrograph. I assume 30 minutes overhead for the change of instruments. Verify the 47/II setup. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem SUNY 08b-10 1 RU Lup 15 56 42.3 -37 49 15.5 11 3x 600 1 39 23 6 SUNY 08b-11 1 V1280 Sco 16 57 41.24 -32 20 36.5 12 3x 900 1 54 23 45 N HAO 08b-01 1 HD165341 18 05 27.3 +02 30 00 4.02 2x 90 1 11 0 39 HAO 08b-01 2 HD190406 20 04 06.2 +17 04 13 5.78 2x 90 1 11 0 50 HAO 08b-01 2 HD165185 18 06 23.7 -36 01 11 5.90 2x 120 1 12 1 1 HAO 08b-01 2 HD165499 18 10 26.2 -62 00 08 5.47 2x 60 1 10 1 13 HAO 08b-01 2 HD172051 18 38 53.4 -21 03 07 5.85 2x 180 1 14 1 23 SUNY 08a-10 1 S CrA 19 01 08.7 -36 57 19.8 11 3x 600 1 39 1 37 HAO 08b-01 1 HD211998 22 24 36.9 -72 15 19 5.29 2x 90 1 11 2 16 cal 1 Feige 110 23 19 58.39 -05 09 55.8 11.8 3x 240 1 21 2 27 STSI 08a-09 2 NGC 246 0 47 03.4 -11 52 19 11.8 3x 300 2 25 2 48 SUNY 05b-09 2 CF Tuc 0 53 7.7 -74 39 5.6 7.6 3x 300 1 24 3 13 HAO 08b-01 1 HD10700 1 44 04.1 -15 56 15 3.49 2x 30 1 9 3 37 HAO 08b-01 1 HD16160 2 36 04.9 +06 53 13 5.79 2x 480 1 24 3 46 HAO 08b-01 1 HD20807 3 18 12.8 -62 30 23 5.23 2x 60 1 10 4 10 HAO 08b-01 2 HD22049 3 32 55.8 -09 27 30 3.72 2x 60 1 10 4 20 HAO 08b-01 2 HD26965 4 15 16.3 -07 39 10 4.42 2x 90 1 11 4 30 HAO 08b-01 2 HD30495 4 47 36.3 -16 56 04 5.49 2x 90 1 11 4 41 STSI TOO 1 M79-3487 5 24 10.35 -24 29 20.6 12.2 3x 300 2 25 4 52 HAO 08b-01 1 HD43834 6 10 14.5 -74 45 11 5.08 2x 90 1 11 5 17 SUNY 07a-03 2 HD 35320 5 23 34.79 -10 25 06.8 7.5 3x 200 1 19 5 28 SUNY 07a-03 2 HD 34993 5 21 09.91 -08 17 05.5 9.2 3x 300 1 24 5 47 SUNY 08a-15 1 sigma Ori 5 38 44.8 -02 36 00 3.8 3x 30 1 10 6 11 HAO 08b-01 2 HD53705 7 03 57.3 -43 36 29 5.55 2x 90 1 11 6 21 HAO 08b-01 2 HD65907 7 57 46.9 -60 18 11 5.59 2x 60 1 10 6 32 cal 1 pflat --- --- 0 10 6 42 PP end 47/II 6 52 If there is any time left before dawn, or you get ahead and have to wait for targets to rise, or if some targets are too faint to acquire, please select from among the following 47/II targets: standard 3 HD224935 0 1 57.5 -06 0 48.6 4.4 3x 60 1 12 standard 3 HD 9053 1 28 22.0 -43 18 55.2 3.4 3x 30 1 10 SUNY 08a-05 2 AB Dor 5 28 44.8 -65 26 54.8 7.0 3x 100 1 14 SUNY 08b-02 3 NY Ori 5 35 37 -05 12 24 15.0 3x 400 1 24 Y SUNY 07a-03 3 HD 39419 5 52 13.37 -06 50 52.9 9.1 3x 300 1 24 SUNY 07a-03 3 HD 40353 5 57 56.07 -06 28 23.1 9.2 3x 300 1 24 HAO 08b-01 3 HD63077 7 45 35.0 -34 10 21 5.36 2x 60 1 10 Just before sunrise, get well-exposed TWILIGHT SPECTRA at zenith. Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: H: target is far to the north. It must be observed within +/- 20 minutes of transit to keep the zenith distance <60 degrees. M: moon within 10 degrees. Skip if the star is not seen in the acquisition TV B: very bright star: best observed through clouds. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. CE: EF Eri is the eastermost star in a pair. The separation is about 25 arcsec. It may be 3 mag fainter than the western star. Please Check the finding chart if in doubt. CP: close pair. Observe both stars. Please take care to identify the stars properly, either by coodinates or relative brightness. E: may be below the east limit if you get to it early. F: faint target may be hard to see with moon up. N: Nova. Will be fainter than on finding chart. PP: if not done at the start of the night. Be sure to get one set of bias frames either at the start of end of the night. R: radial velocity standard. S4: set slit width to 4.0 arcsec. S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. ST: If you cannot observe LTT 4364 early in the evening, please be sure to observe Feige 10 (in the backup list) as the specroscopic calibrator. TC: time critical. maintain spacing between the images TR: 227 arcsec W and 153 arcsec N of center of NGC 300 W: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end. Y: 5 arcsec SE of brighter star. Skip if not clearly resolved. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = absolute highest priority 1 = observe object if possible 2 = extra targets; skip if running behind and Priority 1 targets remain unobserved. 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after; 3 means before, after, and between each exposure. 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 25 minutes for a change in the grating tilt/filter. .............................................................................. Notes about finding charts: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Most charts are available via the link from the main 1.5m scheduling page. Charts for most objects should be available at the telescope. ..............................................................................
