In afternoon or during dinner: - 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) If there is time, set up the echelle Please set the chip readout to read out the full CCD. I allow 2 minutes read time for the full CCD. Please obtain at least 10, and preferably 25, bias and projector flat (quartz) frames. Please do a ThAr lamp exposure with each echelle target. Please set the slit width to 60 microns. If the date is earlier than June 1, start with the regularly scheduled program. If the date is between June 1 and June 24, start with the RC 26/Ia setup. Select from the following targets, and observe until about 1150 LST: Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem SUNY 09a-11 3 N LMC 2009 5 40 44.2 -66 40 12 11 3x 600 1 39 N STSI 09a-02 3 V838 Mon 7 04 04.8 -03 50 50 15.6 3x1000 2 60 STSI TOO 3 V576 Car 8 19 15.7 -60 10 01 10.2 3x 300 2 25 STSI 09a-05 3 0950+13 9 52 59.0 +13 44 34 16.0 3x 400 1 29 STSI 09a-05 3 Lo 4 10 05 45.7 -44 21 32 16.6 3x 900 1 54 SUNY 09a-09 3 HD 109962 12 39 07.89 -45 33 44 9.7 3x 300 1 24 SUNY 09a-11 3 QY Mus 13 16 30 -67 37 0 9.3 3x 300 1 24 N If the date is earlier than June 24 or later, start in with this 26/Ia program: ---------------------------------------------------------------------------- Program Pri Target RA (J2000) Dec mag Exp Cmp T CST Rem cal 1 LTT 4364 11 45 37.70 -64 50 25.1 11.5 3x 200 1 19 SUNY 09a-11 1 U Sco 16 22 30.68 -17 52 42.1 10 3x XX 1 U1 end 26/Ia ---------------------------------------------------------------------------- When done with the above RC spectrograph targets, switch to the echelle spectrograph.

Please do not overexpose any part of the spectrum. A good exposure is 10,000 to 40,000 counts at the peak of the brightest emission line, or in the continuum. U2: Repeat this exposure. About once an hour, obtain a ThAr comparison spectrum. About 35 minutes befor the start of astronomical twilight, go to calibration target HR 7950. U3: Use the exposure time you settled on for U Sco at the start of the night. Please check the exposure level - it may have brightened or faded. Continue to observe for as long as possible into twilight. -------------------------------------------------------------------- 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 CST 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. ..............................................................................
