In afternoon or during dinner: - Install 58/I 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 2132 local time. At 2132 CST, switch to the RC spectrograph. I assume 30 minutes overhead for the change of instruments. Verify the 58/I setup. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem SUNY 08a-18 2 T969_23A 15 12 28.9 -57 17 00.1 12.4 3x 600 1 39 22 2 SUNY 08a-18 2 T1038_2A 16 00 26.4 -52 11 10.0 11.5 3x 600 1 39 22 41 SUNY 08a-18 2 T1434_4A 18 23 32.3 -12 03 58.4 14.4 3x 600 1 39 23 20 SUNY 08a-18 2 T1540_1A 18 53 21.2 -00 59 29.2 13.4 3x 500 1 34 23 59 standard 1 VB 10 19 16 57.6 +05 9 2.2 17.3 3x 600 1 39 0 33 W cal 1 Feige 110 23 19 58.4 -05 09 56 11.8 3x 120 1 15 1 12 STSI TOO 1 NGC 300 0 54 34.16 -37 38 28.6 14.2 3x1000 1 59 1 27 TR SUNY 08a-18 2 SMC11_1B 0 47 25.5 -72 47 41.3 13.9 3x 600 1 39 2 26 SUNY 08a-18 2 SMC11_1C 0 47 22.9 -72 39 12.9 14.3 3x 600 1 39 3 5 SUNY 08a-18 2 SMC11_1A 0 50 48.4 -72 52 29.6 10.9 3x 300 1 24 3 44 SUNY 08a-18 2 SMC10_1A 0 51 10.5 -72 56 05.0 12.8 3x 500 1 34 4 8 SUNY 08a-18 2 SMC15_1A 0 52 11.0 -73 13 55.9 15.5 3x 700 1 44 4 42 SUNY 08a-18 2 SMC15_8A 0 53 19.8 -73 28 54.4 14.6 3x 600 1 39 5 26 SUNY 08a-18 2 SMC15_2A 0 52 12.9 -73 08 52.9 11.3 3x 400 1 29 6 5 cal 1 pflat --- --- 0 10 6 34 PP end 58/I 6 44 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 58/I targets: SUNY 08b-02 3 EX Lup 16 03 05.48 -40 18 25.9 11.4 3x 200 1 14 standard 3 GJ 143.3 3 31 47.1 +14 19 18 12.3 3x 600 1 39 standard 3 HD 42581 6 10 34.6 -21 51 53 8.1 3x 300 1 24 standard 3 HD 14386 2 19 20.8 -02 58 39.5 3.0 3x 5 1 9 standard 3 HD 27598 4 20 41.2 -16 49 50.6 7.0 3x 60 1 12 standard 3 HD 18191 2 55 48.5 +18 19 53.9 5.8 3x 30 1 11 standard 3 HD 19285 3 03 27.7 -58 55 37 7.3 3x 60 1 12 STSI 08b-03 3 PM 48581 20 4 4.8 -65 36 1 11.4 1x 30 1 10 STSI 08b-03 3 PM 48907 20 15 22.7 -56 45 54 12.6 1x 100 1 11 STSI 08b-03 3 PM 52130 21 49 25.9 -63 6 51 13.0 1x 100 1 11 STSI 08b-03 3 PM 52823 22 8 38.6 -83 3 28 13.2 1x 100 1 11 STSI 08b-03 3 PM 53697 22 24 23.0 -65 58 36 12.8 1x 100 1 11 STSI 08b-03 3 PM 58362 23 54 41.3 -61 35 10 13.0 1x 100 1 11 STSI 08b-03 3 PM 58658 23 59 38.8 -73 9 18 12.5 1x 100 1 11 STSI 08b-03 3 PM 58669 23 59 44.8 -44 5 0 12.9 1x 100 1 11 STSI 08b-03 3 PM 5286 1 29 20.9 -85 56 11 13.5 1x 200 1 12 STSI 08b-03 3 PM 6035 1 47 42.5 -48 36 5 13.1 1x 100 1 11 STSI 08b-03 3 PM 6094 1 48 26.2 -56 58 41 12.0 1x 100 1 11 STSI 08b-03 3 PM 6122 1 48 26.0 -70 58 29 12.4 1x 100 1 11 STSI 08b-03 3 PM 6405 1 53 37.1 -66 53 34 11.4 1x 30 1 10 STSI 08b-03 3 PM 10088 3 9 22.2 -39 11 3 12.9 1x 100 1 11 STSI 08b-03 3 PM 10246 3 12 29.8 -38 5 20 11.5 1x 30 1 10 STSI 08b-03 3 PM 10344 3 14 19.7 -34 2 3 12.7 1x 100 1 11 STSI 08b-03 3 PM 10587 3 18 45.5 -40 51 34 13.6 1x 200 1 12 STSI 08b-03 3 PM 10740 3 20 51.8 -63 51 52 13.9 1x 200 1 12 STSI 08b-03 3 PM 11326 3 34 42.9 -48 24 4 13.4 1x 200 1 12 STSI 08b-03 3 PM 11388 3 35 59.7 -44 30 45 12.7 1x 100 1 11 STSI 08b-03 3 PM 12999 4 18 4.7 -49 1 30 13.3 1x 200 1 12 STSI 08b-03 3 PM 13045 4 18 51.0 -57 14 1 13.5 1x 200 1 12 STSI 08b-03 3 PM 13170 4 22 12.5 -57 26 1 11.8 1x 30 1 10 STSI 08b-03 3 PM 13292 4 26 32.7 -30 48 1 13.9 1x 200 1 12 STSI 08b-03 3 PM 13370 4 27 36.2 -59 21 15 13.3 1x 200 1 12 STSI 08b-03 3 PM 13399 4 28 5.7 -62 9 25 13.5 1x 200 1 12 STSI 08b-03 3 PM 13515 4 32 42.6 -39 47 12 12.6 1x 100 1 11 STSI 08b-03 3 PM 13566 4 33 39.7 -51 57 22 13.0 1x 100 1 11 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. ..............................................................................
