APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 6, 2002 (MJD 52281) ---=== OBSERVING TEAM ===--- Atsuko Nitta Scot Kleinman St. Larry Carey Jon Brinkmann David Schlegel via phone Russell Owen via phone ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- There were no "too large to correct" fiducial errors tonight. We changed the collimate update rate from 60s to 5s to help along the actuator A move faster. We got another set of data for plate 799. This time we got data at all pointings. Please make sure the data looks ok even though the weather was not photometric. We tried cartridge 7 plate 769 without success again. We will ask the plate to be remapped. We don't know why we were not able to find even the fk5 star. We finidhsed one plate and got some data on two other plates. ---=== OBSERVING LOG ===--- The nights started out as non-photometric sky, i.e. we cannot do any science since all available plates at the beginning of the night requires photometric condition. We homed the secondary successfully. cartridge 9 plate 799 ---------------------- Scot updated the instruction for observing the stellar plate and checked it in. David, please make read it and make sure you are happy with the changes. Observers, please do cvs update the instruction before observing stellar plates. ~01:00 Scot's sop session got the familiar loosing the instrument problem. 01:00 After restarting and taking the first guider image, the sop hung. But went back to normal after quitting fsaoImage. 01:15 Port snatched away again from sop session. Offsets for each pointing is recorded in the offset section. 799 pointing Again we got 4 out of 5 stars, but had trouble getting 5th star in. We called David to see if there was anything we can do to find out why this is the case. Since there was nothing he or we could come up with, we proceeded to take the requested 3 x 10-min smear. 799B pointing Suppose to have guide stars in 1,4,6. Instead, we saw stars in 6, very dim in 1 and nothing in 4. There is someone at the edge of 11 also. 799C pointing No surprises. The monitor shows there are star light down the fibers. 799D pointing The monitor shows an image more or less like a bias, but checked with idl, there were fibers with light. 799E pointing No surprises. 799F pointing (bd+21) Same as we tried last time, we could not find the star at the initial poitning nor at +-8" in RA. spiralPattern found the star at 20" to the south of the initial pointing. Two decsmears that was requested by David were also completed. cartridge 3, plate 768 photo-z-like plate --------------------------------------------- ~04:22 We centered the guide stars, did preCalib and when we restarted the guider, all the guide stars were not there any more. We ended up having to go to fk5 star. After we found the fk5 star and went back to the science field, Scot's fsaoImage froze sop and he had to exit and restart fsaoImage. Severl minutes later, sop lost the instrument. His sop session also could not understand any abbreviations any more (like startMon was not recognized, but startMonitor was.) He restarted fsaoImage and then found no guid stars. It turns out that the actuator A wasn't keeping up again. The collimation did bright the actuator to its proper position and we were able to resume operation. We dragged St. Larry who has just gone to bed to let him know the situation. Since we told him that our workaround has been to issus "proc enable colimate" to hurry the actuator A along, he decided to ask Russel if TCC can be modified to have the collimation process run more often. Russel was actually surprised that we only had the auto-collimate running for every 60 sec. He told us how to modify this and we modeified it to every 5 sec. You can check how often the auto-collimate is running by typing in telrun session, show block tune and look for "Collimate_Interval". This info is folklored. Now with faster update, TCC telrun session looks busier. cartridge 7 plate 769 ------------------------ This is the plate that Steph and Scot could not find stars last night. We tried again without success. fk5InFiber did not find the fk5 star. A long integration did not help. A spiralPattern didn't find anything. There was no too large to cross fiducial errors while slewing to this plate. We gave up on this plate and moved on to th next one. We don't know why we cannot find any stars. We will ask this plate to be remapped just in case something went wrong there. The manuplator would refuse to move while preparing cartridge 2. It was at the left end of the rail and when I tried to move to the right, it would not move and give me "beep beep beep". Scot manually moved the manipulator a bit to the right and then it moved in normal manner. Was it stuck to something?? cartridge 2 plate 768 ------------------------- We did not find any guide stars at initial pointing. But we found the fk5 star whose position was off by was 8". FYI, there was no too large to correct fiducial errors slewing to this field. The sky started to clear while we were observing this plate and we were able to finish it. First plate finished this dark run! cartridge 6 plate 328 -------------------------------- ~09:50 Actuator A was a bit slow while setting up and we issued "proc enable collimate" although we don't know if it was really necessary or not. We had to go to fk5 star to find the field. Again there was no fiducial too large message while slewing to the field. Probably due to the moonlight, there are many scattered light and red monster warnings from sos for the red camera. Therefore, the (s/n)^2 for the red data is much smaller than those for the blue data. We did not take smear for this plate --- it was not photometric and the plate is not done yet anyway. endNight ran successfully. ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 00:40 12480 0.0 bias ----- sequence 12481, plate 799 ------- 01:34 12481 10.0 flat 01:36 12482 2.0 arc 01:52 12483 600.0 smear 02:07 12484 600.0 smear 02:22 12485 600.0 smear 02:37 12486 120.0 smear 02:45 12487 120.0 smear 02:50 12488 120.0 smear 02:59 12489 9.0 smear 03:01 12490 9.0 smear 03:04 12491 9.0 smear 03:17 12492 2.0 smear 03:19 12493 2.0 smear 03:22 12494 2.0 smear 03:28 12495 1.0 smear 03:31 12496 1.0 smear 03:33 12497 1.0 smear 03:48 12498 1.0 smear 03:51 12499 1.0 smear 03:53 12500 1.0 smear 03:56 12501 10.0 flat 03:58 12502 2.0 arc 04:04 12503 2.0 smear 04:08 12504 2.0 smear ----- sequence 12505, plate 804 ------- 04:22 12505 10.0 flat 04:24 12506 2.0 arc 05:04 12507 901.0 target 05:32 12508 1501.0 target 06:00 12509 1501.0 target 06:28 12510 1501.0 target 06:35 12511 240.0 smear ----- sequence 12512, plate 768 ------- 07:03 12512 10.0 flat 07:05 12513 2.0 arc 07:35 12514 1503.0 target 08:07 12515 1802.0 target 08:35 12516 1501.0 target 09:08 12517 1802.0 target 09:31 12518 1202.0 target 09:39 12519 240.0 smear 09:41 12520 10.0 flat 09:43 12521 2.0 arc ----- sequence 12522, plate 328 ------- 09:58 12522 10.0 flat 10:00 12523 2.0 arc 10:23 12524 1202.0 target 10:57 12525 1805.0 target 11:30 12526 1801.0 target 12:04 12527 1862.0 target 12:37 12528 1800.0 target 12:39 12529 10.0 flat 12:41 12530 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ 18:31 9 799 1010367075 0.003794 -0.000844 -0.000905 0.999900 19:32 9 799B 1010370749 0.003316 -0.002201 0.000209 0.999900 20:00 9 799C 1010372402 0.004975 -0.001353 0.012577 1.000000 20:15 9 799D 1010373322 0.006944 -0.001285 0.012577 1.000000 20:26 9 799E 1010373994 0.007657 -0.001038 0.012577 1.000000 20:46 9 799F 1010375170 -0.002533 -0.005547 0.012577 1.000000 21:51 3 804 1010379110 0.004536 0.000486 -0.004099 0.999950 00:09 2 768 1010387340 0.000406 -0.001949 -0.018715 0.999950 03:04 6 328 1010397884 0.004073 -0.001026 -0.013613 0.999910 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 21:53 3 804 0.99995 493 1589 0 -40 49.9 -1.3 8 342 2" 00:19 2 768 0.99995 493 1565 0 140 58.4 -1.3 20 348 1.5" 03:06 6 328 0.99991 888 1921 0 35 48.7 -1.3 23 32 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 16:49 33 13 1 243 (WSW) 56 - 17:21 30 12 4 351 (NNW) 58 - 17:52 31 13 1 2 (N) 62 - 18:22 30 12 1 97 (E) 59 - 18:52 31 12 2 235 (SW) 85 - 19:22 30 11 4 254 (WSW) 78 - 19:52 30 11 5 271 (W) 65 - 20:23 30 13 6 354 (NNW) 34 - 20:53 29 14 14 5 (N) 34 - 21:23 30 15 22 353 (NNW) 32 - 21:53 29 16 8 342 (NNW) 44 - 22:23 30 17 10 23 (NNE) 44 - 22:55 30 17 10 41 (NE) 61 - 23:25 30 17 4 0 (N) 48 - 23:56 29 17 19 359 (NNW) 48 - 00:27 29 18 19 8 (N) 45 - 00:57 29 18 15 9 (N) 47 - 01:29 28 17 18 9 (N) 46 - 02:01 30 19 15 13 (NNE) 36 - 02:32 29 18 16 6 (N) 48 - 03:02 29 19 24 22 (NNE) 43 - 03:33 30 17 17 17 (NNE) 25 - 04:05 31 16 19 14 (NNE) 22 - 04:37 30 18 23 16 (NNE) 19 - 05:09 31 17 18 34 (NE) 18 - 05:39 31 17 24 20 (NNE) 22 - 06:09 31 18 25 23 (NNE) 14 - ---=== TELESCOPE STATUS ===--- Fans on and doors opened around 23:45.
