APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 5, 2006 (MJD 53741) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Kaike Pan Howard Brewington Phone: Steph Snedden Steve Kent ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Declared five plates done, viz., 1501, 1513, 2071, 2315, and 2366. Completed 17S, -60 to -30 (does not include 2-degree ramps) We also did part of 1540S, i.e., 168 to 188 (does not include 2-degree ramps) Unfortunately, skippy would not work for this segue stripe because there was no koTycho2-1540.fit file on sdsshost2; see log. These data will need to be checked for pointing accuracy. The star-catalog file /p/tycho2/v1_0/ko/koTycho2-1540.fit is missing, and we may need it during the next shift because this is the only late night stripe. Could someone please move it to sdsshost2? ---=== Log ===--- Afternoon: ----------- No problems with the afternoon check. Spectrograph focus checked and set for slightly lower temps. Now set for 1 to 2 C. Details in problem section. Cartridge 1 mounted on telescope. 23:30Z Doors Open, Louvers Open, Fans On 00:20Z Enclosure Open Night: ------------ 01:07Z Cart 01, 1502 (merged73). Guide stars on goToField. Plate declared done with four exposures. 03:36Z Cart 02, plate 1513 (merged73). An FK5 was used to find the field. Plate declared done with three exposures. 04:56Z Cart 06, plate 2071 (seguefaint105). Guide stars on goToField. Plate declared done after tonight's S/N^2 was added to last night's; see below.

After this stripe, we moved on to 1540S; unfortunately, we had a problem when we ran skippy; see error message below. astrom> skippy 5973 13 1 ERROR: oldAstrom: oldAstrom: can't find known object catalog '/p/tycho2/v1_0/ko/ koTycho2-1540.fit' NONE oldAstrom: can't find known object catalog '/p/tycho2/v1_0/ko/koTycho2-1540.fit' while executing "error "oldAstrom: can't find known object catalog '$catalog'"" invoked from within "if {[file exists $catalog] == 0} { error "oldAstrom: can't find known object catalog '$catalog'" }" ("foreach" body line 3) invoked from within "foreach cat $koFile { set catalog $koDir/$cat if {[file exists $catalog] == 0} { error "oldAstrom: can't find known object catalog '$catal ..." ccd dmu(") dnu(") dmag Error: Error processing FITS file asPMerge-005973.fit Error opening FITS file asPMerge-005973.fit We checked on sdsshost and sdsshost2 for the koTycho2-1540.fit file; however, it did not exist. So, we did not know if our pointing is okay. We contacted Steph S. and Steve Kent. They suggested that we let the scan continue. Steve also looked on the machines a fnal for the missing file but had no luck. We were pointing close to the part of the sky of the previous stripe done tonight, so we are using the same offsets as before. We hope these data are good but have no way to know. Misc. Watcher messages are in the Problems Section. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame

Note: Best focus temperature can only reliably be determined by comparing against PSS temp using sp1. When the telescope has been at stow for an extended period (say all day), sp2 gets quite a bit colder (as much as 2 or 3 C) presumably due to the boil off of the camera dewars above the spectrograph body in this orientation. Note: When collimate is run in version v5_1_0 there is a warning message "speclog_version: Command not found." It doesn't appear to effect the calculations but is not seen in v4_10_7.
