----------------------------------------------------------------------- INSTRUMENT SETUP 2012A SCHAEFER - 13 April 2012 - CTIO 0.9m queue observing ----------------------------------------------------------------------- CONDITIONS: PHOTOMETRIC CCD: FULL 13.7'x13.7' READOUT: ONE AMP GAIN INDEX: 3: Read Noise ~ 3.5 ADU = 3.5 e- FILTER SET: UBVRI CALIBRATION FRAMES: BIAS - 10 DOME FLAT V 5 ~20000 counts DOME FLAT R 5 ~20000 counts DOME FLAT I 5 ~20000 counts SKY FLAT U 3 > 5000 counts SKY FLAT B 3 >10000 counts ----------------------------------------------------------------------- NOTES FOR TARGET FIELDS ----------------------------------------------------------------------- The dark of night is 11 hours long, and my half night is thus 5.5 hours. IF PHOTOMETRIC, then my 5.5 hours of observations can be run almost anytime of the night. You must start before 05:00 UT (so as to get the full half night). You are free to switch the order of the targets or choose alternative Landolt fields depending on your judgment of conditions. You can work a bit into twilight and through poor seeing, but it must be photometric. If it turns non-photometric during the middle, then just switch over to the time series in the non-photometric program. ----------------------------------------------------------------------- NOTES FOR CALIBRATION FIELDS ----------------------------------------------------------------------- If photometric, observe the Landolt fields in UBVRI as described in the OBSERVING SEQUENCE section. ----------------------------------------------------------------------- OBSERVING SEQUENCE ----------------------------------------------------------------------- TARGET PG1323-085 (Landolt field) PRIORITY 1 COORDINATES 13:25:39 -08:49:16 (J2000) FINDER CHART http://www.cfht.hawaii.edu/ObsInfo/Standards/Landolt/PG1323.gif AIRMASS This should be not far from zenith FILTER(S) V, R, I, B, U INTEGRATION(S) 30s, 30s, 30s, 60s, 60s TOTAL TIME 10 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET G292.0+1.8 PRIORITY 1 COORDINATES 11 24 33.9 -59 15 40.4 (J2000) FINDER CHART none available, go by setting circles AIRMASS observe only when above 2.0 airmass FILTER(S) 2 X (V, R, I, B, U) INTEGRATION(S) 2 X (300s, 300s, 300s, 600s, 600s) TOTAL TIME 90 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET PG1047+003 (Landolt field) PRIORITY 1 COORDINATES 10:50:03 -00:00:32 (J2000) FINDER CHART http://www.cfht.hawaii.edu/ObsInfo/Standards/Landolt/PG1047.gif AIRMASS This should be not far from zenith FILTER(S) V, R, I, B, U INTEGRATION(S) 30s, 30s, 30s, 60s, 60s TOTAL TIME 10 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET G299.2-2.9 PRIORITY 1 COORDINATES 12 14 54.7 -65 28 33.2 (J2000) FINDER CHART none available, go by setting circles AIRMASS observe only when above 2.0 airmass FILTER(S) 2 X (V, R, I, B, U) INTEGRATION(S) 2 X (200s, 200s, 200s, 300s, 400s) TOTAL TIME 60 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET PG1323-085 (Landolt field) PRIORITY 2 COORDINATES 13:25:39 -08:49:16 (J2000) FINDER CHART http://www.cfht.hawaii.edu/ObsInfo/Standards/Landolt/PG1323.gif AIRMASS This should still be above 2.0 airmass FILTER(S) V, R, I, B, U INTEGRATION(S) 30s, 30s, 30s, 60s, 60s TOTAL TIME 10 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET RCW 86 PRIORITY 2 COORDINATES 14 43 00 -62 30 00 (J2000) FINDER CHART none available, go by setting circles AIRMASS observe only when above 2.0 airmass FILTER(S) 2 X (V, R, I, B, U) INTEGRATION(S) 2 X (400s, 400s, 400s, 700s, 700s) TOTAL TIME 90 minutes NOTES Only if photometric and airmass better than ~2.0 TARGET PG1047+003 (Landolt field) PRIORITY 3 COORDINATES 10:50:03 -00:00:32 (J2000) FINDER CHART http://www.cfht.hawaii.edu/ObsInfo/Standards/Landolt/PG1047.gif AIRMASS This should be not far from zenith FILTER(S) V, R, I, B, U INTEGRATION(S) 30s, 30s, 30s, 60s, 60s TOTAL TIME 10 minutes NOTES Only if photometric and airmass better than ~2.0 - - - - - - - - - - - - - - - End Template - - - - - - - - - - - - - -
