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. .............................................................................. Start with the alpha Cen echelle program At 21:25 CST, configure the echelle for queue mode Please set the chip readout to read out the full CCD. Please REMOVE the iodine cell. Please do a ThAr lamp exposure before each set of echelle observations. ** NOTE: the column headed "S" contains the slit width in tens of microns. For example, S=9 means to set the slit width to 90 microns. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST S Rem SUNY 09b-11 1 V1280 Sco 16 57 40.91 -32 20 36.4 13 3x1200 1 71 21 35 9 N SUNY 09b-11 1 V2672 Oph 17 38 19.68 -26 44 14.0 11 3x1200 1 71 22 46 9 NN SUNY 09b-11 1 N Sgr 2009 18 7 8 -33 46 36 7.5 4x 900 1 72 23 57 9 N VAND 09b-01 1 EBLM5 20 44 16.50 +14 37 50.7 11.1 2x 900 1 38 1 9 9 VAND 09b-01 1 EBLM3 21 33 51.55 +17 14 47.2 11.3 2x1050 1 43 1 47 9 W VAND 09b-01 1 EBLM2 21 20 47.97 -40 54 39.8 10.4 1x 900 1 22 2 30 9 VAND 09b-01 1 EBLM4 23 08 45.66 -46 06 36.6 11.4 2x1050 1 43 2 52 9 VAND 09a-01 1 HD1461 00 18 41.87 -08 03 10.8 6.5 1x 60 1 7 3 35 9 *** Please insert the Iodine Cell for the following CN 09b-49 targets Please reset the slit width to 60 microns I allot 10 minutes for this cal 1 insert I2 0 0 0 -50 0 0 10 3 42 6 I CN 09b-49 1 HIP 343 0 04 19.79 -16 31 44.53 5.7 1x 300 1 12 3 52 6 I CN 09b-49 1 HIP 671 0 08 17.53 -08 49 26.80 5.9 1x 300 1 12 4 4 6 I CN 09b-49 1 HIP 4587 0 58 43.87 -11 22 47.91 5.6 1x 300 1 12 4 16 6 I CN 09b-49 1 HIP 6537 1 24 01.41 -08 10 59.72 3.6 1x 300 1 12 4 28 6 I CN 09b-49 1 HIP 11791 2 32 09.42 -01 02 05.67 5.3 1x 300 1 12 4 40 6 I CN 09b-49 1 HIP 17351 3 42 50.06 -37 18 48.67 4.5 1x 300 1 12 4 52 6 I CN 09b-49 1 HIP 17738 3 47 56.04 -30 10 04.38 5.5 1x 300 1 12 5 4 6 I CN 09b-49 1 HIP 19511 4 10 47.76 -08 49 11.33 5.7 1x 300 1 12 5 16 6 I CN 09b-49 1 HIP 21743 4 40 06.80 -24 28 56.53 5.5 1x 300 1 12 5 28 6 I CN 09b-49 1 HIP 22860 4 55 06.82 -16 44 26.41 5.7 1x 300 1 12 5 40 6 I CN 09b-49 1 HIP 24679 5 17 40.24 -13 31 11.37 5.4 1x 300 1 12 5 52 6 I CN 09b-49 1 HIP 26649 5 39 49.84 -32 37 45.18 5.4 1x 300 1 12 6 4 6 I CN 09b-49 1 HIP 27243 5 46 27.37 -46 35 49.85 5.3 1x 300 1 12 6 16 6 I end echelle queue 6 28 ---------------------------------------------------------------------------- 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. I: Please use the Iodine cell for the CN 09b-49 targets. N: Nova. Will be fainter than on finding chart. NN New nova. Coodinates are good to about 15 arcsec. Should be the brightest object in the vicinity R: radial velocity standard. 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. ..............................................................................
