Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. Remember to take a comp spectrum too. -------------------------------------------------------------------- Remarks: M: moon within 10 degrees. Skip if not visible in the acquisition TV A: target reaches 2 air masses at end of exposure. Do not start late; do the calibration lamp at the end if it helps. B: very bright target. C: cataclysmic variable. May be fainter than in finding chart. Skip if not visible. E: target far to the east. If running ahead, give extra time to the previous target, or observe a backup target if time permits. F: faint target may be hard to see with moon up. N: Nova. Will be fainter than on finding chart. O: offset target along slit. O-20 means offset by -20 arcsec from the present position. Do not recenter the target first. PM: may have significant proper motion. R: radial velocity standard. S: set slit width to 4.0 arcsec; reset when done with target V1: VANF 06a-04 program: This is a sequence of 9 observations of PKS1216-010 with the target at different positions along the slit. Each observation is 300 seconds long. Take an comparison lamp after the last exposure in the sequence. The sequence takes about an hour to complete. You will do it 4 times. observation # Target position along slit offset slew 1 centered -- 2 +5" Offset +5" 3 -5" Offset -10" 4 +10" Offset +15" 5 -10" Offset -20" 6 +15" Offset +25" 7 -15" Offset -30" 8 +20" Offset +35" 9 -20" Offset -40" V2: VANF 06a-04 program standards: This is a sequence of 3 observations of a standard with the target at 3 different positions along the slit. Take an comparison lamp after the last exposure in the sequence. observation # Target position along slit offset slew 1 centered -- 2 +10" Offset +10" 3 -10" Offset -20" W: star very close to 2 air masses at end of observation. Don't start late. Y: 5 arcsec SE of brighter star. Try to keep the brighter star out of the slit. Skip if the seeing is really bad. Z: monitoring target. Try to maintain spacing between observations. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. + = absolute highest priority 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after .............................................................................. Notes about finding charts: RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Many charts are available via the link from the main 1.5m scheduling page. Charts for many objects should be available at the telescope. ..............................................................................
