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.

Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. Remember to take a comp spectrum too. -------------------------------------------------------------------- Remarks: X: 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 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. 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. CT: Faint transients. Check finding chart. If you cannot see anything at the position in the chart, skip the target and replace with backup targets 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: target is very faint. It may not be visible through clouds or with poor seeing. If so, please replace it with targets from the backup list. N: Nova. Will be fainter than on finding chart. NN: new nova. No finding chart available. Should be the brightest star near the coordinates (positional uncertainty +/- 2 arcsec). PP: if not done at the start of the night. Be sure to get one set of bias frames either at the start of end of the night. R: radial velocity standard. N3: 227 arcsec W and 153 arcsec N of center of NGC 300 ST: if you cannot observe the standard, please try to observe another cal star (in the backup list) at some other time during the night. S4: set slit width to 4.0 arcsec. Center on the nucleus of the galaxy. S5: set slit width to 5.0 arcsec. Center on the nucleus of the galaxy. S2: set slit width to 2.0 arcsec. Center on the nucleus of the galaxy. Reset the slit to the normal width for the wavecal. S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. S16: set slit width to 16.0 arcsec. Please reset at the end of the observation. T: Time critical. Please try to start these observations close to the requested time. 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: Far north. May exceed 2 AM if you do not get to it on time. Skip it if it it at >2 AM. 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. *: if clouds preclude observations of the fainter targets, and all the backup targets have been observed, you may take a long sequence (nx300) of observations of S CrA. -------------------------------------------------------------------- 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; 3 means before, after, and between each exposure. 0 means NO wavecal should be taken. .............................................................................. 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. ..............................................................................
