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. 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. 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. TC: time critical. maintain spacing between the 3 images W: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end. X: Both of these SUNY 07a-07 targets must be observed. If you cannot acquire the fainter star, or you do not have enough time left to do both, then do not start. Instead, replace them with backup targets from the following list: standard 3 Gl 9322 10 14 08.3 +03 09 05 7.7 3x 200 1 19 PM standard 3 Gl 393 10 28 55.6 +00 50 28 9.6 3x 300 1 24 PM standard 3 HD 99491 11 26 45.3 +03 00 47.2 6.5 3x 100 1 14 standard 3 HD 99492 11 26 46.3 +03 00 22.8 7.6 3x 200 1 19 standard 3 HD102438 11 47 15.8 -30 17 11 6.5 3x 100 1 14 standard 3 Gl 447 11 47 44.4 +00 48 16 11.1 3x 400 1 29 PM standard 3 HD103932 11 57 56.2 -27 42 25 7.0 3x 100 1 14 standard 3 HD108754 12 29 42.7 -03 19 58.7 9.0 3x 300 1 24 standard 3 HD108849 12 30 21.0 +04 24 59.2 8.2 3x 300 1 24 standard 3 HD111631 12 50 43.6 -00 46 05 8.5 3x 300 1 24 standard 3 HD112758 12 59 01.6 -09 50 03 7.6 3x 240 1 21 standard 3 HD114606 13 11 21.4 +09 37 34 8.7 3x 300 1 24 standard 3 HD117176 13 28 25.8 +13 46 44 5.0 3x 30 1 11 standard 3 Gl 514 13 29 59.8 +10 22 38 9.0 3x 300 1 24 standard 3 HD126868 14 28 12.1 -02 13 41 4.8 3x 30 1 11 SUNY 06b-10 1 RU Lup 15 56 42.3 -37 49 15.5 11 3x 600 1 39 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 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. ..............................................................................
