-01 Afternoon calibrations using blackbody source. Start with some 20 sec dark frames. Note that the room and set-up are not perfectly dark. SRM. 01 Dark. Appears to be some light getting through the fibers. 50 cts peak. 02 Dark 03 Dark -04 Testing exposure times for blackbodies. 04 BB source, 110C, test exposure @ 3 SUTR. 100 ADU at peak. 05 BB source, 110C, test exposure @ 30 SUTR. 1900 ADU at peak. 06 BB source, 110C, test exposure @ 20 SUTR. 1250 ADU at peak. 07 BB source, 130C, test exposure @ 20 SUTR. 3800 ADU at peak. -08 Starting sequence of 110C blackbody exposures. 08 BB source, 110C, test exposures @ 20 SUTR. 1250 ADU. Note strange reference level in some quadrants of the blue chip especially. 09 BB source, 110C. 1250 ADU at peak. 10 BB source, 110C. 11 BB source, 110C. 12 BB source, 110C. 13 BB source, 110C. 14 BB source, 110C. 15 BB source, 110C. 16 BB source, 110C. 17 BB source, 110C. -18 Starting sequence of 120C blackbody exposures. 18 BB source, 120C. 2000 ADU at peak. 19 BB source, 120C. 20 BB source, 120C. 21 BB source, 120C. 22 BB source, 120C. Lights may have been turned on by operator during end of exposure. -23 Take a break while operator turns on lights for telescope inspection. 23 BB source, 120C. Louvres in basement now open, so daylight coming in. Some excess light seems to be visible. 24 BB source, 120C. Louvres in basement now open, so daylight coming in. Some excess light seems to be visible. -25 Do another set of 120C BB frames after twilight. 25 BB source, 120C. 2000 ADU at peak, but note that the flux is somewhat lower now than 2 hours ago, probably because of light leaks in the 2.5-m basement even with the louvres closed. -26 After further investgation, it looks like exposure 25 is a bit low and the following exposures are indeed more like exposures 18-22. Make sure to compare all of these 120C exposures against each other to get a good set! Perhaps frames 18-22 and frames 26-30. 26 BB source, 120C. 27 BB source, 120C. 28 BB source, 120C. 29 BB source, 120C. 30 BB source, 120C. -31 Starting sequence of 130C blackbody exposures. Note again funny reference levels on the blue chip of the first exposure in the series. 31 BB source, 130C. 3400 ADU at peak. 32 BB source, 130C. 33 BB source, 130C. 34 BB source, 130C. 35 BB source, 130C. 36 BB source, 130C. -37 Starting sequence of 150C blackbody exposures. 37 BB source, 150C. 10,000 ADU at peak. 38 BB source, 150C. 39 BB source, 150C. 40 BB source, 150C. 41 BB source, 150C. 42 BB source, 150C. -43 Start beginning of the night cal sequence. 43 Dark -- blue persistence at around 250 ADU from BB exposures. 44 Dark -- blue persistence at around 200 ADU from BB exposures. 45 Dark -- blue persistence at around 160 ADU from BB exposures. 46 QTH -- can't tell what effect blue persistence may have on this frame. 47 QTH -- can't tell what effect blue persistence may have on this frame. 48 QTH -- can't tell what effect blue persistence may have on this frame. 49 ThAr -- blue persistence still visible between arc lines at 250 ADU. 50 UNe -- blue persistence still visible between arc lines at 500 ADU -51 Begin science observing: Peter, Ana, Viktor, Olena, Steve -51 Plate 4829, FirstLight2 I, Cart 1, visit 4, 3 visits last month 51 Seeing=2.1", clear skies, S/N = 25.7. 54 Seeing=1.6", S/N = 25.5. 58 Seeing=1.5", S/N = 59 Skyflat, offset 0.01 deg RA 60 Domeflat, 2400 ADU 61 Dark 62 Dark 63 Dark -64 Plate 4947, 004-04, Cart 5, first visit (2 broken fibers 77,128) 64 Seeing=2.4" 65 Seeing=2.3", S/N = 27.1. 68 S/N = 25.0 70 S/N = 27.4 72 Domeflat, 2500 ADU 73 Dark 74 Dark 75 Dark -76 Plate 4951, 018-02, Cart 3, first visit 76 Seeing=1.7", S/N = 30.3 77 Odd comment after STUI disconnect, S/N = 31.0 80 Seeing=1.3" 84 Domeflat, mistake on lamps, 3000 ADU 85 Domeflat, 2200 ADU 86 Dark 87 Dark 88 Dark -89 Plate 4938, 090+04, Cart 4, second visit 89 S/N = 28.4 92 S/N = 27.1 95 Domeflat, 2500 ADU 96 Dark 97 Dark 98 Dark -99 Run end of night cals -99 END CALS BAD, Gang Connector not Plugged In!!!!!
