In afternoon or during dinner, set up the echelle: Please set the chip readout to read out the full CCD. Please obtain at least 10, and preferably 25, bias and projector flat (quartz) frames. Then, set up the RC - Install 26/Ia grating setup - check focus if necessary - obtain at least 25 Zero frames - obtain at least 10, preferably 25, flat-field frames (projector or dome) .............................................................................. Start with the alpha Cen echelle program At 22:48 CST, please set up the 26/Ia RC mode. I assume 20 minutes for the switchover. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem SUNY 09a-10 1 S CrA 19 01 08.7 -36 57 19.8 11 3x 300 1 24 23 8 TC SUNY 09a-10 1 RX J1655-32 16 15 20.23 -32 55 5.1 12 3x 300 1 24 23 32 SUNY 09a-02 2 EX Lup 16 03 05.48 -40 18 25.9 11.4 3x 300 1 24 23 56 SUNY 09a-10 1 V2129 Oph 16 27 40.32 -24 22 02.7 11.4 3x 300 1 24 0 20 SUNY 09a-11 1 V1280 Sco 16 57 40.91 -32 20 36.4 13 4x 600 1 50 0 44 N,W SUNY 09a-11 1 V5558 Sgr 18 10 18.27 -18 46 52.1 8 4x 600 1 50 1 34 N,W SUNY 09a-10 2 V4046 Sgr 18 14 10.5 -32 47 34.5 11 3x 300 1 24 2 24 SUNY 09a-10 1 S CrA 19 01 08.7 -36 57 19.8 11 3x 300 1 24 2 48 SUNY 09a-01 2 HU Aqr 21 7 58.22 -05 17 40.1 16 11x 300 1 72 3 12 C cal 1 Feige 110 23 19 58.39 -05 09 55.8 11.8 3x 240 1 21 4 24 CN 09a-27 1 TONS180 00 57 19.94 -22 22 59.1 3x 180 1 20 4 45 S10 STSI 09a-05 2 NGC 246 0 47 03.4 -11 52 19 11.8 3x 300 1 25 5 5 SUNY 09a-01 2 BL Hyi 1 41 00.3 -67 53 27.7 14.9 3x 300 1 24 5 30 C SUNY 08a-05 1 AB Dor 5 28 44.8 -65 26 54.8 7.0 3x 60 1 12 5 54 SUNY 09a-02 1 NY Ori 5 35 37 -05 12 24 15.0 3x 600 1 39 6 6 Y end 26/Ia 6 45 ---------------------------------------------------------------------------- If time remains at the end of the night, please select from among the following targets: SUNY 04a-09 3 HD 22468 3 36 47.3 +00 35 16 5.9 3x 100 1 14 SUNY 09a-02 3 V1118 Ori 5 34 44.66 -05 33 41.3 16.5 3x 600 1 39 SUNY 09a-02 3 V1143 Ori 5 38 03.8 -04 16 42 16.8 3x 600 1 39 ---------------------------------------------------------------------------- At the end of the night, please obtain at least 10, and preferably 25, projector flat (quartz) frames with the full chip readout. if you did not take them earlier. ---------------------------------------------------------------------------- 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 E: may be below the east limit if you get to it early. N: Nova. Will be fainter than on finding chart. R: radial velocity standard. S6: Please set slit width to 60 microns 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 W: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end. -------------------------------------------------------------------- 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. ..............................................................................
