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 B: very bright target. Best observed through clouds. 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: there is no finding chart for this bright star. NN: New nova. No finding chart. This will be the brightest thing around. N: Nova. Will be fainter than on finding chart. R: radial velocity standard. S2: set slit width to 2.0 arcsec. Be sure to center on the nucleus of the galaxy. S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. No wavecal is necessary with this exposure. PM: may have significant proper motion. W: star very close to 2 air masses at end of observation. Don't start late; do the calibration lamp at the end if it helps. X: you may do more than 3 observations if you need more fillers at low latitudes. 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. ..............................................................................
