APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 30, 2005 (MJD 53521) ---=== OBSERVING TEAM ===--- Steph Snedden (swing) John Barentine Mike Harvanek ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did some imager cals (uLeak for u3). Finished 1 plate (1714). We may have finished another plate (2174). Please see the log for details on the uncertainty of this plate's status. Could the Segue people (Brian Yanny?) please have a look at 2174 and determine if this plate is done or not. If this plate is done, please notify the pluggers ASAP so they can replug this cartridge. Also, if this plate is declared done, someone needs to update the database. Got good data on another plate (1655). ---=== OBSERVING LOG ===--- Swing shift: ----------- A normal swing shift. No problems. De-millermothed one altitude drive surface. Spectrograph focus was not adjusted, but tilts were slightly tweaked. See the appropriate section at the end of the log. Night: ------ Mostly cloudy at sunset so we begin with imager calibrations. John had the following problem when trying to set up for the imager cals: > set sdsscvs > setup sdsscvs > umask 002 > cd /usrdevel/jcb/msp > cvs co msp sdssprd.fnal.gov: Connection timed out rsh: connection failed cvs [checkout aborted]: end of file from server (consult above messages if any) This message occurred in multiple attempts in 2 different windows. We got around the problem by having John copy Mike's msp directory. We did uLeak QE for u3. The details are given below: u3 leak QE: ----------- Run # 5356 Frame # Comments ------- -------- 1 bias 1 2 bias 2 3 dark 1 4 dark 2 5 360. 0.0 6 360. -30.0 7 360. 30.0 8 370. 30.0 9 380. 30.0 10 450. 30.0 11 500. 30.0 12 550. 30.0 13 600. 30.0 14 640. 30.0 15 660. 30.0 16 680. 30.0 17 690. 30.0 18 700. 30.0 19 710. 30.0 20 720. 30.0 21 730. 30.0 22 740. 30.0 23 870. -30.0 24 870. 0.0 25 750. 30.0 26 760. 30.0 27 765. 30.0 28 770. 30.0 29 774. 30.0 30 778. 30.0 31 782. 30.0 32 786. 30.0 33 790. 30.0 34 795. 30.0 35 800. 30.0 36 810. 30.0 37 820. 30.0 38 830. 30.0 39 850. 30.0 40 870. 30.0 41 900. 30.0 42 950. 30.0 43 450. -30.0 44 450. 0.0 All data and analysis are stored in /data/photo/doi/calibdata. The skies cleared while we were doing imager cals and we immediately went to spectroscopy when the cals finished. Plate 1714 (cartridge 5): Survey. Guide stars on the gotoField. This plate was finished in 3 exposures (2900 sec total). SoS warned of max sky residuals twice. The call for a postCal came too late. Plate 1655 (cartridge 7): Survey. Guide stars on the gotoField. Clouds and variable seeing hampered efficiency. We were not able to finish this plate before it expired but we got 3 good exposures (3300 sec total). Plate 2174 (cartridge 1): Segue. Glow of guide stars on the gotoField. We were able to acquire the guide stars with a +5" offset in RA (no FK5 was needed). We obtained at least 1 good exposure (32907). We are uncertain if the next two exposures (32908, 32909) are good or not. Both of these frames had S/N^2 < 2 for r2. However, when determining if Segue plates are done, we look at only the blue S/N^2 and so it is unclear if anyone cares about the red S/N^2. If only the blue signal is important, we believe this plate is done (b1=13.4, b2=32.8 when combining data from last night and tonight). however, if the red signal is important, this plate may not be done. We request that the Segue people (Brian Yanny?) have a look at this plate and determine its status. If this plate is done, please notify the pluggers ASAP so they can replug this cartridge. Also, if this plate is declared done, someone (observers? jcb?) needs to update the database. Finally, note that SoS gave many warnings (whopping fibers, sky residuals, scattered light) for this plate. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5355 22:20Z 22:36Z 100 O -67.17 -63.30 40 ignore 5357 06:58Z 07:10Z 100 O 62.64 65.72 27 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== 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 32881, plate -9999 ------- 23:08 32881 0.0 bias ----- sequence 32882, plate 2174 ------- 23:28 32882 10.0 flat 23:30 32883 2.0 arc 23:56 32884 2.1 arc 23:58 32885 2.1 arc 00:18 32886 10.0 flat 00:21 32887 2.0 arc 00:35 32888 10.0 flat 00:37 32889 2.0 arc 00:45 32890 2.1 arc 00:47 32891 2.1 arc ----- sequence 32892, plate -9999 ------- 01:24 32892 0.0 bias 01:27 32893 0.0 bias ----- sequence 32894, plate -9999 ------- 02:23 32894 0.0 bias ----- sequence 32895, plate 1714 ------- 17.4 16.0 19.2 16.8 DONE 06:58 32895 10.0 flat 07:00 32896 2.0 arc 07:19 32897 900.2 target 07:37 32898 900.1 target 07:58 32899 1100.1 target ----- sequence 32900, plate 1655 ------- 11.8 10.6 15.4 10.9 not done 08:12 32900 10.0 flat 08:14 32901 2.0 arc 08:33 32902 900.1 target 08:56 32903 1200.1 target 09:19 32904 1200.1 target ----- sequence 32905, plate 2174 ------- Data from both tonight and 09:36 32905 10.0 flat last night (53520).

The X and lambda tilts were a bit off, although low NGOODFIBERs complicated the issue. I made some conservative tweaks in both X and lambda tilt, basing the adjustments on the cameras that had the best NGOODFIBER numbers. Before adjust: sp1 sp2 A= 304 -1665 B= 503 -1465 C= 6 -2563 After X adjust: A= 106 -1865 B= 305 -1664 C= 216 -2363 After lambda adjust: A= 106 -1765 B= 305 -1764 C= 216 -2363
