APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday November 23, 2005 (MJD 53698) ---=== OBSERVING TEAM ===--- Howard Brewington John Barentine Mike Harvanek (swing) Jon Brinkmann - support Craig Loomis (by phone) ---=== OBSERVING PLAN ===--- Supernova science. ---=== OBSERVING SUMMARY ===--- An on-again, off-again night, weather-wise, but we bravely trudged on and images SN Stripe 82 N from +115 < lambda < -125 (plus ramps). Both cloud density and seeing varied significantly during this drift so we're uncertain of its value, but we did at least clear the 100-frame threshold in sufficiently clear skies to run skippy. We waited out the weather until about one hour before morning twilight before packing it in for the night. ---=== OBSERVING LOG ===--- Afternoon: ---------- The tccmon wouldn't run normally this afternoon. Jon Brinkmann discovered that the initialization wasn't being performed. The fix is to issue the following command after tccmon: source /home/neilsen/tccmon/etc/init.tcl It was also discovered that watcher wouldn't run. Jon Brinkmann called Craig Loomis and they solved the problem. This also solved the tccmon problem and so the workaround given above is not necessary. Thanks to Jon and Craig for their late afternoon support. (See Problems section for Craig's secret solution). We're still getting the warning about NaN value for IPARATE in spectro fits header for the flats and arcs but not for the biases: 2005-11-23 22:47:58Z: NaN value for IPARATE in spectro fits header 2005-11-23 22:50:16Z: NaN value for IPARATE in spectro fits header A formal spectro collimation check was not performed (supernova night) but a postCal showed all the xsigma/wsigma values to be in spec. The spectrographs are currently collimated for a temp of approximately +2 degrees C. Night: ------ The imager was mounted shortly before sunset and a bias was taken in the darkened enclosure. Run 5897: On-telescope bias in a darkened enclosure. Everything looked okay. 00:58Z Run 5898 (SN Stripe 82 N, startLambda=+109). We began ramping earlier than we would have otherwise on instructions from Steph to get a third night's data point with the rotation evidently misaligned according to the pointer (by ~30 arcminutes). This jives with the minutes of today's telecon in which we were told to NOT correct pointing errors on the fly on SN nights because it causes problems in the data reduction. Fortunately, last night's offsets were retained in the TCC and we did not require a pointing correction. Skippy was happy from the start of this run but some issues with the focus loop persisted right up until the proper start of the ramp at Frame 33, lambda=+113, RA=298, 01:16Z. Our expected focus value was way off from the actual number, by about 200 steps, so there was some flailing to get it "close" such that the focus loop could take over. We decided to call it in focus at Frame 34, so slightly into the ramp but not far enough, we thought, to warrant backing up and ramping again. Science began at 01:24Z, Frame 46, lambda=+115, RA=300. Ramped down from lambda=-125 (Frame 847) to end the drift at lambda=-123 (Frame 861). We're not sure how much of this run will be useful because of intermittent waves of clouds. 07:25Z We note a discrepancy in the values of the dust concentration reported in displayweath. There is about a factor of two difference between what is reported for the tower dust counter and the 3.5m enclosure dust counter. We checked with Jack (3.5m observing specialist extraordinaire), who confirmed that the 3.5m pressurization fans were NOT on at the time. The difference in dust counts is probably real and related to a counter in need of calibration. After the SN drift ended, we had mostly cloudy skies. It was too thick to do even spectro, but no rain threatened on radar. We parked the telescope at stow and closed the flat field screens in case of the need to close quickly. Clouds stayed thick for the next couple of hours. We dismounted the imager and put a cartridge on with < 1.5 h until twilight, deciding that if conditions had not changed significantly by the time we finished the instChange, we were very likely done for the night. We also rolled the enclosure over the telescope as a safeguard. Called it a night at 11:30Z. A sucker hole had opened above us but satellite indicated it was sure to be short-lived. endNight rejoiced.... ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5896 22:41Z 22:59Z 100 O 112.37 116.95 45 ignore 5898 01:00Z 09:31Z 82 N 109.19 -122.69 870 science Clouds through most (Bias run 5897 did not appear automatically here.

Nope. tccMon? Maybe. (If you're lucky.) Craig!!!! --------------------------------------------------------------- Here's Craig's explanation for what he did to fix our watcher/tccMon problem this afternoon: After I rudely flung that recent watcher PR back, Jon called to gently point out that tccMon still didn't work. So I looked a bit more carefully, and found that we had bumped into a ups feature which I think merits highlighting for those (like me) who weren't weaned on this stuff. Basically, when you declare a product with "ups declare", you need to explicitly specify the table file, or the table file (as conventionally installed in SDSS products) will not be processed when the product is setup. No table file at setup means no version dependancies and no environment setup (which is why WATCHER_STARTUP was no longer available for tccMon to redefine). The ups option in question is "-m TABLENAME". Here's a gory example, where I redeclare the existing watcher product as vScratch. ========= First, without the -m -- note that ups warns you that you are in trouble ================== [cloomis@sdsshost2 watcher]$ ups declare -r /linuxp/prd/watcher/v2_31_0 -f `ups flavor` watcher vScratch INFORMATIONAL: Product 'watcher' (with qualifiers '*'), has no table file Specification did not include a -m for table file only default actions will be performed [cloomis@sdsshost2 watcher]$ less /linuxp/db/watcher/vScratch.version FILE = version PRODUCT = watcher VERSION = vScratch #************************************************* # FLAVOR = Linux+2.4-2.3.2 QUALIFIERS = "" DECLARER = cloomis DECLARED = 2005-11-23 23.35.11 GMT MODIFIER = cloomis MODIFIED = 2005-11-23 23.35.11 GMT PROD_DIR = /linuxp/prd/watcher/v2_31_0 UPS_DIR = ups =============== Now with the -m ========================= [cloomis@sdsshost2 watcher]$ ups undeclare watcher vScratch [cloomis@sdsshost2 watcher]$ ups declare -r /linuxp/prd/watcher/v2_31_0 -f `ups flavor` -m watcher.table watcher vScratch [cloomis@sdsshost2 watcher]$ less /linuxp/db/watcher/vScratch.version FILE = version PRODUCT = watcher VERSION = vScratch #************************************************* # FLAVOR = Linux+2.4-2.3.2 QUALIFIERS = "" DECLARER = cloomis DECLARED = 2005-11-23 23.36.22 GMT MODIFIER = cloomis MODIFIED = 2005-11-23 23.36.22 GMT PROD_DIR = /linuxp/prd/watcher/v2_31_0 UPS_DIR = ups TABLE_FILE = watcher.table See the TABLE_FILE line -- that's what you want to see. There may be cases where it is not necessary, but I'd expect them to be rare exceptions. I checked the major products, and they all had a TABLE_FILE line. - craig (Muchas gracias, Senor Loomis!)
