We finished four plates (2399, 2404, 2370, 2141), obtained partical signal on one plate (2374) and imaged SEGUE stripe 1540 from +147 mag 15. Efficiency was good on this plate and we backed the fourth exposure off from 30 min to 20 min. Finished the plate with a low (S/N)^2 of 53.2, again in r1. 07:05Z Cart 7 Plate 2370 (tile 1696, chunk131) GSOGTF with an additional offset of A=-5 beyond the sticky offsets from the previous plate. Clouds started to come in from the SW during the setup on this plate. Done in 3 x 900 s exposures with a low (S/N)^2 of 15.8 (that pesky r1...) Seeing an opportunity to image, we took it. We appeared to be in a ribbon of clear sky between cloud bands separated (we believed) by about 2 to 2.5 hours. Switched at 08:15Z but then on setup of the imager we immediately had a problem issuing the goDrift command: im> goDrift Flavor of this run (science, bias, calibration, engineering, ignore, help) []: science Stripe, Strip (e.g, 22,N or SS,N) [17,N]: Please provide a one line comment [] go Error: called "eqToStripe" with too many arguments (A full traceback of the error is in the Problems section along with the solution.) Called Eric, who walked us through diagnostics and then a fix. This involved two aborted drifts (Run 5997 for one frame and Run 5997 for 3 frames). 09:10Z Run 5999 (SEGUE stripe 1540, startMu=+147) Skippy happy from the start, as was focus. Seeing was a little shaky at the beginning but trending down to within spec by about frame 20. Ramp began at Frame 22, Mu=+149.5, and science at Mu=+153. We continued imaging but we had both thin clouds moving in and seeing that was never reliably "good" according to seeingRun. We ended the drift at Frame 106 (Mu=+162). 10:07Z Run 6000 (On-telescope bias) Switched back to spectroscopy at 10:30Z. 10:40Z Cart 4 Plate 2374 (Tile 1700, chunk131) GSOGTF. Clouds and an early expiry of this plate made us pull it after one exposure of 1200 s. 11:35Z Cart 9 Plate 2141 (Tile 1547, chunk109). No GSOGTF but found an fk5InFiber number 10 with an additional offset of A=-4, D=+3. We did two exposures of 1200 and 600 s, bringing us up to about 1/2 hour before twilight. Without enough time to finish this plate, mount another cartridge, setup on the field and get in a single exposure before pushing too far into twilight. We decided to take an extra 600 s exposure to get additional signal on this plate, then call it a night. Finished with more than enough signal on this plate. Closed up for the night at 13:00Z. endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5996 23:36Z 23:51Z 100 O -168.62 -164.94 39 ignore 5997 08:34Z 08:35Z 100 O -33.75 -33.50 16 ignore 5998 08:57Z 09:01Z 17 N -68.68 -67.82 19 ignore 5999 09:08Z 10:08Z 1540 S -37.71 -22.60 114 science 6000 10:12Z 10:26Z 100 O -9.13 -5.62 38 bias ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 5998 8 4 0 0.000 0.000 0.000 0.000 -0.00000 0 0 5999 11 4 11 -9.100 1.132 9.500 1.980 0.05472 178 32 5999 29 4 87 6.800 0.231 1.800 0.183 -0.02069 180 35 5999 47 4 75 6.300 0.190 1.600 0.131 -0.01816 181 37 5999 63 4 66 6.000 0.189 1.400 0.138 -0.01574 182 39 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 5999 22 1 34 1 39 -1.362 0.358 2.909 0.251 -0.00978 5999 22 1 34 1 39 -1.091 0.178 2.922 0.258 -0.00982 5999 22 1 34 1 26 -0.710 0.261 2.803 0.289 -0.00942 5999 22 1 34 1 30 -0.352 0.164 3.076 0.197 -0.01034 5999 22 1 34 1 28 -0.038 0.349 3.092 0.309 -0.01040 5999 22 1 34 1 39 -1.362 0.358 2.909 0.251 -0.00978 5999 22 1 34 1 39 -1.091 0.178 2.922 0.258 -0.00982 5999 22 1 34 1 26 -0.710 0.261 2.803 0.289 -0.00942 5999 22 1 34 1 30 -0.352 0.164 3.076 0.197 -0.01034 5999 22 1 34 1 28 -0.038 0.349 3.092 0.309 -0.01040 5999 38 1 36 359 29 -1.974 0.335 2.126 0.310 -0.00715 5999 38 1 36 359 21 -1.719 0.207 2.370 0.220 -0.00797 5999 38 1 36 359 25 -1.386 0.202 2.428 0.177 -0.00816 5999 38 1 36 359 27 -1.013 0.248 2.597 0.279 -0.00873 5999 38 1 36 359 23 -0.555 0.412 2.653 0.235 -0.00892 5999 72 1 41 356 16 -1.150 0.429 1.944 0.583 -0.00654 5999 72 1 41 356 25 -1.068 0.348 2.031 0.487 -0.00683 5999 72 1 41 356 18 -0.572 0.345 2.523 0.486 -0.00848 5999 72 1 41 356 26 -0.211 0.356 2.562 0.417 -0.00861 5999 72 1 41 356 14 0.089 0.283 2.863 0.194 -0.00963 5999 90 1 43 354 22 -0.747 0.238 2.027 0.249 -0.00681 5999 90 1 43 354 19 -0.365 0.333 2.078 0.216 -0.00699 5999 90 1 43 354 15 -0.241 0.253 2.283 0.211 -0.00768 5999 90 1 43 354 12 0.212 0.313 2.307 0.220 -0.00776 5999 90 1 43 354 19 0.784 0.268 2.357 0.281 -0.00792 ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 36823, plate -9999 ------- 23:21 36823 0.0 bias 23:25 36824 0.0 bias 23:28 36825 0.0 bias ----- sequence 36826, plate 0 ------- 23:31 36826 10.0 flat 23:33 36827 2.0 arc N.B.: The "Plate 0" was the result of not having loaded the cartridge before taking a postCalib, and the data were not reduced in SoS.
