These are faint galaxies and we can always use more observing time! :) RVSTDS=Radial velocity standards (bright galaxies). Observe before (after) 18- degree evening (morning) twilight. For the morning object, obtain comp after observation. OFFSET=Please note that there is a faint star right on top of the galaxy nucleus. So, for these objects, offset the galaxy from the slit so that the nucleus+star are not observed. CHECK!=This galaxy is in a very crowded region with stars within 5 arcseconds. Please refer to the 2MASS finding charts provided in the project web page (http://www.noao.edu/staff/lmacri/smarts/ under "IR" column) to make sure you center on the galaxy and *not* on a nearby star. ---------------------------------------------------------------------------- If there is any time left before dawn, or you get ahead and have to wait for targets to rise, or if some targets are too faint to acquire, please select from among the following 9/Ib targets: SUNY 07a-11 2 V1280 Sco 16 57 41.24 -32 20 36.5 9.9 3x 30 1 10 N SUNY 07a-09 3 HD 109962 12 39 07.89 -45 33 44 9.7 3x 100 1 14 cal 3 LTT 4364 11 45 37.7 -64 50 25.1 11.5 3x 100 1 14 SUNY 07a-11 3 V1065 Cen 11 43 10.3 -58 4 4.3 8 3x 60 1 12 N standard 3 HD 88824 10 13 22.8 -51 13 59 5.3 3x 5 1 9 standard 3 HD 89707 10 20 50.0 -15 28 48 7.2 3x 20 1 10 standard 3 HD102870 11 50 41.6 1 45 53 3.6 3x 2 1 9 standard 3 HD110379 12 41 39.6 -01 26 57.9 3.7 3x 2 1 9 Just before sunrise, get well-exposed TWILIGHT SPECTRA at zenith IF you could not obtain them at dusk. 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 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: finding chart under SUNY 07A-04 charts . i: I magnitude; V is about 20. 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 S3: set slit width to 165 (3.0 arcsec). S10: set slit width to 10.0 arcsec. Please reset at the end of the observation. No wavecal is necessary with this exposure. T: monitoring target. Try to maintain spacing between observations. 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. Y: 5 arcsec SE of brighter star. Try to keep the brighter star out of the slit. Skip if the seeing is really bad. -------------------------------------------------------------------- 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. ..............................................................................
