Cross/Oblique scan done, then 19N done in two runs (5182, 5183) from -66 -> 51.5 (that is including ramps). We left the imager mounted ont the telescope. EndNight was left running on landru, please take care about tapes - thank you. No problems to report. ---=== OBSERVING LOG ===--- Swing: ============== The afternoon checkout went well; except, I got a critical error that sp1 had low pressure and a warming CCD. I reported the problem to Jon Brinkman. See Problem Section for details. Spectro focus was checked but not adjusted; see Problems Section for focus numbers. Night: ============== The imager was mounted at the evening. We set up for the cross/oblique scan and started it very early (~35 minutes before the twilight end), timing it so we'd reach the desired start just before twilight: TRACK 83.8200, 11.5000 FK5 /SCANVELOCITY=(0.00000000,-0.00417807) /KEEP=(BORESIGHT) Run 5181 (offsets from the previous night were cleared and xbore offset was accepted): 02:07Z Dec reached 6 deg. at frame 39. In Focus, seeing good ~1.4". We are ~25 minutes in the twilight. Dec 4 at frame: 51. 02:29Z Frame 76 end of the twilight. 02:59Z Frame 125, dec -7. 03:07Z Frame 138, dec -9, end of the drift. Seeing still good. Thanks, Peregrine for the nice nebulosity show. Run 5182: We went for the stripe 19 N (the next highest priority strip available). Scan started at lambda -68. Boresight offset accepted. Seeing good, focus good. 03:18Z Frame 19, lambda -66, begining of the ramp. 03:26Z Frame 33 lambda -64. Skippy is happy. At frame 138 the seeing get worse, but still acceptable (lambda -48.2). Frame 147 Longitude -46.8 bad seeing started. 05:16Z Lambda -36. The seeing got improved. We ended the drift and moved the telescope to lambda -52. 05:20Z Run 5183, the above stripe 19 N scan is continued here. In focus, good seeing since the beginning. skippy is happy :). Bad seeing: Frame 29 Longitude -48.4 -> Frame 68 Longitude -42.6 Then seeing good till the end of the run. 12:11Z Frame 697, lambda 51.5 drift ended (~10 minutes in the twilight). 12:14Z run 5184, bias with the imager on the telescope. 12:35Z The telescope put to the stow positions, with imager on. spectro and imager dewars refilled. EndNight is running, while we are leaving. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5180 22:39Z 23:30Z 100 O -143.32 -130.51 44 ignore 5181 01:48Z 03:08Z 100 O -95.81 -75.89 147 calibration 5182 03:11Z 05:17Z 19 N -67.79 -36.06 226 science 5183 05:20Z 12:13Z 19 N -51.66 51.94 705 science 5184 12:14Z 12:34Z 100 O 61.07 65.98 47 bias ---=== IMAGING RUN DETAILS ===--- Cross/Oblique scan (run 5181): done.

After I reported the problem to Jon Brinkman, I did a cc 4 tcheck and got the following: sp1> cc 4 tcheck CAMERA 4 LN2 TEMP NOMINAL 77 K MEASURED 144 K CCD TEMP DAC SET AT 115 = -0.52 V = -90 C MEASURED -80 C Next I did: cc startfillseq, and the chip started to cool after a few minutes as reported below. sp1> cc 4 tcheck CAMERA 4 LN2 TEMP NOMINAL 77 K MEASURED 108 K CCD TEMP DAC SET AT 115 = -0.52 V = -90 C MEASURED -80 C However, the chip started to warm again a few minutes later. So, French and Jon replaced a some kind of a power cable on sp1, which repaired the problem. ---== Spectro Focus Numbers ==--- IDL 5.5a> collimate, 31293 Reading /data/spectro/53439/sdR-b1-00031293.fit Reading /data/spectro/53439/sdR-b1-00031294.fit COLLIMATE: Min offset = -0.77 pix COLLIMATE: Max offset = 0.96 pix COLLIMATE: RMS across CCD = 0.47 pix COLLIMATE: Mean offset = 0.16 pix COLLIMATE: Camera b1 appears to be OUT-OF-FOCUS (|mean| > 0.15 pix) COLLIMATE: Predict blue camera ring movement of -5.6 degrees for spectro-1 COLLIMATE: (if red is already in focus) Log file = Collimate-53439-b1-00031293.log PostScript file = Collimate-53439-b1-00031293.ps Reading /data/spectro/53439/sdR-b2-00031293.fit Reading /data/spectro/53439/sdR-b2-00031294.fit COLLIMATE: Min offset = -0.26 pix COLLIMATE: Max offset = 0.40 pix COLLIMATE: RMS across CCD = 0.17 pix COLLIMATE: Mean offset = 0.06 pix COLLIMATE: Camera b2 appears to be IN-FOCUS (|mean| 0.15 pix) COLLIMATE: Predict (red) piston movement of 2032 steps for spectro-1 COLLIMATE: Issue SOP command: "sp1; mechPiston 2032" Log file = Collimate-53439-r1-00031293.log PostScript file = Collimate-53439-r1-00031293.ps Reading /data/spectro/53439/sdR-r2-00031293.fit Reading /data/spectro/53439/sdR-r2-00031294.fit COLLIMATE: Min offset = -0.61 pix COLLIMATE: Max offset = 0.15 pix COLLIMATE: RMS across CCD = 0.16 pix COLLIMATE: Mean offset = -0.11 pix COLLIMATE: Camera r2 appears to be IN-FOCUS (|mean|
