APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 13, 2003 (MJD 52987) ---=== OBSERVING TEAM ===--- Mike Harvanek Atsuko Kleinman Jon Brinkmann (by phone) Dan Long (by phone) Eric Neilsen (by phone) ---=== OBSERVING PLAN ===--- Shakedown and science. ---=== OBSERVING SUMMARY ===--- We obtained a 62 point pointing model with rms = 1.81. This was verified with a 20 point model with rms = 1.16 The new guider code was tested successfully. It passed shake and is ready to use. Thus, iop/sop version v3_124_0 was declared current. We obtained good data for one plate (1564). SEGUE iop was tested but the goDrift on the SEGUE strip failed as did skippy. Eric Neilsen came up with a fix for the goDrift problem and will check in his changes ASAP. However, skippy still does not work and SEGUE iop still needs more work. PR 5656 was closed because stripeAxisRates appeared to work on SEGUE, northern and southern stripes but no other SEGUE PRs were closed. It was too bright to obtain JEG's donuts at the position requested. We took some donuts from the SEGUE strip area. Although the collimation seems a bit off it did not seem worth correcting. The new version of SoS appeared to work ok but we gave it very little to reduce (a few low z plate exposures and a few survey plate exposures). Further testing is needed (i.e., plates with more than a standard number of sky fibers) before the associated PR can be closed. ---=== OBSERVING LOG ===--- Afternoon checkout went smoothly. Since we did not get on the sky last night, we began with the engineering camera to get a pointing model. While trying to focus the engineering camera, it was noticed that the secondary was not moving. We tried homing the secondary but this failed as well. The error messages are in the problems section. Jon Brinkmann was called and he suggested cycling power for the M2 galils. We did this and then rehomed the secondary and all was well. For the pointing model, we used GRID_9_8_27_88_T_30_FN.DAT;1 During the first attempt at the pointing model we got the following: altitude (correction for altitude -30696 is too large (2003-12-14 01:45:26Z sdssmcp): 2003-12-14 01:45:41Z) While making the first attempt at the pointing model, it was noticed that the rotator type was object and not horizon. So, the first attempt was aborted, the rotator type was corrected and we started over. From the instructions in the procedure, there was still some confusion as to whether things were working properly using horizon for the rotator type. Dan Long was called and he said that we should be using object for the rotator type. Although it may take a little longer, he believes that using object for the rotator type produces a better model. Although the procedure says to use horizon, we know that Dan's pointing models are good and so we aborted the second attempt and started over using object for the rotator type. Although we used the same 72 point grid mentioned above, the pointing model ended data taking after only 25 points. There did not appear to be any errors and it seemed to end normally and successfully. It just ended prematurely. Perhaps this had something to do with us aborting the 2 previous attempts. So, we attempted another pointing model using GRID_8_8_25_88_T_90.DAT;1 Got the following during this pointing model: azimuth (correction for azimuth 318260 is too large (2003-12-14 03:40:57Z sdssmcp): 2003-12-14 03:41:18Z) The 64 point grid mentioned above completed successfully. One point was not measured and one was removed as an extreme outlier. When the 62 remaining points were fit, rms = 1.81. To verify the model we used GRID_5_4_25_80_T_30.DAT;1 Got the following during this pointing model: altitude (addoffset: Max accl. for altitude exceeded: -237/1000 (2003-12-14 04:09:07Z sdssmcp): 2003-12-14 04:09:27Z) rotator (addoffset: Max accl. for rotator exceeded: 287/1000 (2003-12-14 04:46:44Z sdssmcp): 2003-12-14 04:47:01Z) The 2nd model had an rms = 1.16. It started to cloud up near the end of the 2nd pointing model. While the SEGUE on-sky tests do not require photometric conditions, they do require enough stars for skippy to run so we decided to switch to spectroscopy and shake the new guider code while attempting science. Plate 1564 (cartridge 5): An fk5 was needed to acquire the guide stars. We obtained 2 good exposures (1800 s total) before this plate expired. The new guider code appeared to work fine and it passed all shake tests. Plate 1272 (cartridge 8): Guide stars on the gotoField. There was an error message about the flat exposure being too faint during the first attempt at a preCalib. A second try at the preCalib seemed to work. See the Problems section for details. We tried 2 exposures (900 s each) but there was too much moon. None of the remaining available plates had a moon unit less than 2. Fortunately, the clouds had thinned some so we decided to mount the imager and do the SEGUE tests and perhaps JEG's donuts. Using the SEGUE iop, we scanned a northern strip for 21 frames. Skippy ran successfully. We then tried the SEGUE strip: scanStripe 205 N -mu 80. The telescope appeared to move to the proper coordinates but the goDrift failed. See the Problems section for details. We woke Eric Neilsen who suggested we call Brian Yanny. We called Brian Yanny but got his answering machine. Eric called back and tried to help us debug the problem. We tried issuing a goDrift -bias but got stars! Perhaps the previous goDrift that had failed had left the shutter open. We ended the drift and tried another goDrift -bias. This time we got a bias. Whew! Eric came up with a patch and we tried the goDrift again. We got a similar error message but this time the drift started. Eric will check in his fix ASAP and notify us when it is ready. Skippy did not run for the SEGUE strip but ltmatch appears to have worked. There were also problems with runs getting recorded into the Imaging Summary portion of the log (see that portion of the log for details). Is this another SEGUE iop problem? We moved the telescope into position for JEG's donuts but the moon was less than 25 degrees away and was getting closer. We didn't feel comfortable opening the shutter in these bright conditions so we moved the telescope back to the SEGUE strip and took some donuts for a collimation check. While the collimation appears to be a little off, it did not appear to be worth adjusting as the difference in fwhm for the same filters across all dewars was not more than 0.25" for any filter. The donut frames were saved as follows: Donut frames under nonphotometric conditions and moon are in /data/photo/optics/52987.
