Civil date Setup Program(s) Jul 26 echelle SUNY 09a-10 SUNY 09a-14 The queue program starts at 1900 LST (23:00 CST), .............................................................................. 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 23:10 CST, configure the echelle for queue mode Please set the chip readout to read out the full CCD. Please set the slit width to 140 microns. Please REMOVE the iodine cell. Please do a ThAr lamp exposure before each set of echelle observations. ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem SUNY 09a-14 1 TYC5631_1007 16 33 41.64 -09 33 10.5 10.5 3x1200 1 72 23 10 SUNY 09a-14 1 TYC0523_0573 20 39 54.55 +06 20 12.7 10.5 3x1200 1 72 0 22 SUNY 09a-10 2 S CrA 19 01 08.7 -36 57 19.8 11 3x1200 1 72 1 34 SUNY 09a-14 1 TYC1158_1185 22 42 48.87 +13 30 52.9 11.5 3x1200 1 72 2 46 STSI 09a-05 2 NGC 246 0 47 03.4 -11 52 19 11.8 3x 600 1 42 3 58 SUNY 09a-14 1 TYC1766_1431 2 23 26.57 +22 44 07.9 11.4 3x1200 1 72 4 40 SUNY 04a-09 1 AB Dor 5 28 44.8 -65 26 54.8 7.0 8x 300 1 54 5 52 end echelle queue 6 46 ---------------------------------------------------------------------------- If time remains at the end of the night, please continue taking 300 sec exposures of AB Dor. ---------------------------------------------------------------------------- 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 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. 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. Y: 5 arcsec SE of brighter star. Try to keep the brighter star out of the slit. Skip if the seeing is really bad. -------------------------------------------------------------------- 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. ..............................................................................
