Civil date Setup Program(s) Nov 13 echelle GSU 08b-09 NOAO 08b-02 SUNY 08b-08 SUNY 08b-15 .............................................................................. This night combines two programs: - the NOAO 08b-02 program is a series of calibration spectra of the full moon, taken with the 65 micron slit and through the Iodine cell. Use the standard partial chip readout used for the alpha Cen program. - The SUNY program uses both the 150 and 65 micron slits, and does NOT use the iodine cell. Use the full chip readout. - The two programs use different file naming conventions. For the NOAO program, please set the observation prefix to "qa03." and the starting observation number to be 1000. For the other observations, use the standard SMARTS naming conventions. In afternoon or during dinner: NOAO program setup: 1) In the afternoon, warm up the iodine cell (the cell will be in the light path for the moon observations). Remember that the temperature controller sometimes overshoots (and then alarms) when the cell is cold - just turn it off, let the temperature drift below 55 and then restart it. 2) Set the spectrometer slit to the nominal value (65 microns, I think). Please check this and let us know the setting. 3) setting up ARCON: Set the observation prefix to be: "qa03." and the starting observation number to be 1000. The readout should be in the fastest mode. 3) For calibration, I would like to have a ThAr spectrum, and 30 Quartz lamp spectra (e.g., taken in the afternoon). The Iodine cell should be out of the light path for these calibration. SUNY program setup: 4) Set the spectrometer slit to 150 microns. 5) Use the full chip readout 6) Reset arcon to use the SMARTS naming conventions 7) Take a series of at least 11 quartz lamps 8) Take 3 dusk sky spectra about sunset. Take a Th-Ar wavecal too. 9) Please do a ThAr lamp exposure with each echelle target.

(contact debra.fischer@gmail.com in the case of questions) 1) Set the spectrometer slit to the nominal 65 microns. 2) Use the standard partial chip readout 3) Reset arcon to use the qa03 prefix 4) Center on the full moon 5) Take a ThAr lamp exposure with the Iodine cell OUT of the beam 6) For the actual observation, the I2 cell should be put in the light path. Once the moon has been acquired, slew toward the center of the moon. There are no special instructions, except that it's best to position the slit over a region that is somewhat uniformly illuminated. Exposure times should be 90 seconds. Guiding will need to be done by hand, of course, and I would like a set of 50 observations.

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. E: target far to the east. If running ahead, give extra time to the previous target, or observe a backup target if time permits. M: moon within 10 degrees. Skip if not visible in the acquisition TV 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). R: radial velocity standard. 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. 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; 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. ..............................................................................
