Details in Log. 11:39Z GSOGTF for all 4 MARVELS fields observed after the implementation of the new pointing model. Observed the following MARVELS fields under photometric conditions with seeing ranging from 1.5" to 2.0" FWHM: cart. 3, 4517 A & B cart. 1, 4521 A & B ---- Observing Log ---- 04:49Z Afternoon: --------- 23:20Z - started ventilation; doors opened. The flex engineering schedule called for a pointing model tonight, followed by MARVELS. Since Craig and Paul indicated they had no tests for the first few hours, the only BOSS checks were a bias and dark. The bulk of afternoon checkout time was then given to the analysis and installation of new fiducial tables based on this morning's data from Bob. v1_91 of mcp_fiducials was installed. 05:02Z Engineering camera mounted. 00:30Z - Opened enclosure. Night: ----- 11:34Z Point Model *********** After opening, we forced a fill from the 180L LN2 dewars and started the DIMM. When the fill finished, we tweaked the counter-weights (set them to ~215 after we mounted the engCam, but before filling the spectrographs) and crossed fiducials in all axes to make sure everything was reading (the 45-deg. alt. fiducial was not reading just as it was not reading during the taking of fiducial crossing data in the afternoon). We started the ecamera actor and ensured that we could take data with 'tcc gcam doread 5' and images were in fact being written to /data/ecam/55580/. At this point we were ready to go with the pointing model. We took a 72-point grid of pointing data and afterwards we weren't entirely sure whether we had cleared the calib offsets prior to the onset of data taking. We think we had, but since we had the time and since the seeing was variable during the data collection we cleared all offsets and started again. Here are the tpoint results from the first grid of pointing data: * getdat PTERR_20110119.DAT;2 Read 72 data points * fix * use ie ia pzzl an aw ca Invalid coefficient name: 'PZZL' ! ? * use ie ia pzz1 an aw ca * fit coeff change value sigma 1 IE +2.218 -8.23 1.022 2 IA -0.340 -76.75 1.666 3 PZZ1 +1.149 -134.23 1.257 4 AN -1.488 +3.53 0.405 5 AW -0.197 -10.36 0.405 6 CA -22.234 -18.68 1.164 7 TX -4.68 8 HWCA2 -0.80 9 HWSA2 +0.68 10 HNCA1 -0.61 11 HNSA1 -0.17 12 ACEC -0.85 13 ACES +3.19 Sky RMS = 2.98 Popn SD = 3.11 * use * fit coeff change value sigma 1 IE -1.577 -9.81 1.358 2 IA +0.282 -76.47 1.483 3 PZZ1 -0.900 -135.13 4.484 4 AN +0.807 +4.34 0.468 5 AW -0.369 -10.73 0.458 6 CA -0.476 -19.15 1.099 7 TX +0.278 -4.41 2.156 8 HWCA2 -0.321 -1.12 0.601 9 HWSA2 -0.534 +0.15 0.621 10 HNCA1 +2.320 +1.71 0.699 11 HNSA1 +0.803 +0.63 0.698 12 ACEC -1.101 -1.95 0.843 13 ACES -2.611 +0.57 0.853 Sky RMS = 2.57 Popn SD = 2.84 The second grid of 72-point produced the following results: * getdat [tcc.pterr]PTERR_20110119.DAT;5 Read 72 data points * fix * use ie ia pzz1 an aw ca * fit coeff change value sigma 1 IE +0.568 -9.24 0.908 2 IA -0.899 -77.37 1.477 3 PZZ1 +0.467 -134.67 1.118 4 AN -0.554 +3.79 0.361 5 AW -0.696 -11.42 0.360 6 CA +1.034 -18.12 1.032 7 TX -4.41 8 HWCA2 -1.12 9 HWSA2 +0.15 10 HNCA1 +1.71 11 HNSA1 +0.63 12 ACEC -1.95 13 ACES +0.57 Sky RMS = 2.66 Popn SD = 2.78 * use * fit coeff change value sigma 1 IE +1.049 -8.19 1.333 2 IA -0.294 -77.66 1.469 3 PZZ1 +1.672 -132.99 4.454 4 AN -0.336 +3.45 0.465 5 AW +0.218 -11.20 0.456 6 CA +0.316 -17.80 1.088 7 TX -0.715 -5.12 2.158 8 HWCA2 +0.784 -0.34 0.599 9 HWSA2 +0.476 +0.63 0.617 10 HNCA1 -1.068 +0.64 0.696 11 HNSA1 -0.299 +0.33 0.694 12 ACEC +0.334 -1.62 0.841 13 ACES +0.925 +1.50 0.849 Sky RMS = 2.56 Popn SD = 2.83 During collection of the second set of data the seeing remained variable (DIMM reporting about 1.5" seeing on average). We installed this pointing model. Finally, we took a 20-point grid to check the pointing with the implementation of the new pointing model and the analysis from tpoint is as follows: * getdat [tcc.pterr]PTERR_20110119.DAT;6 Read 20 data points * fix * use ie ia pzz1 an aw ca * fit coeff change value sigma 1 IE -1.053 -9.25 1.209 2 IA -0.749 -78.41 1.887 3 PZZ1 -1.320 -134.31 1.377 4 AN +0.803 +4.25 0.514 5 AW +0.388 -10.82 0.515 6 CA +0.717 -17.09 1.383 7 TX -5.12 8 HWCA2 -0.34 9 HWSA2 +0.63 10 HNCA1 +0.64 11 HNSA1 +0.33 12 ACEC -1.62 13 ACES +1.50 Sky RMS = 1.97 Popn SD = 2.35 * use * fit coeff change value sigma 1 IE +0.827 -8.42 1.909 2 IA -0.078 -78.49 1.748 3 PZZ1 +3.568 -130.75 5.260 4 AN -0.117 +4.14 0.609 5 AW +0.045 -10.77 0.566 6 CA -0.288 -17.37 1.307 7 TX -1.548 -6.67 2.236 8 HWCA2 +0.114 -0.23 0.798 9 HWSA2 -0.334 +0.29 0.888 10 HNCA1 +0.149 +0.79 1.004 11 HNSA1 +1.256 +1.59 0.973 12 ACEC +0.191 -1.43 0.987 13 ACES +0.710 +2.21 1.028 Sky RMS = 1.82 Popn SD = 3.07 07:30Z - Switched to MARVELS.
