Scans failing processing: none Scans failing ACT reconstruction: NONE Darks & Flats: Taken Used Diagnostics/Notes ----- ---- ----------------- Darks morn no camera was warming up, resultant darks were not used. Flats flats were taken, but were not used for processing since they were contaminated with clouds. The nightly/scan-by-scan overview pages are at: http://irsatest.ipac.caltech.edu:8001/data/2mass/lgos/qa990623n General: -------- Observer reported - Clouds at sunset. Scattered clouds until 0511 UT. One cal set taken at 0348 UT, but then observing halted until 0510 UT. Clouds visible again to the E and NE at 1045 UT, and move overhead by 1155 UT. May have influenced twilight flats that were begun at 1135 UT. - Reflection reported in scan 027 (frames 35-45; moon?). - Satellite reported in scans 053 (fr 11-13). - Camera warmed slightly in the morning after observing. Partial night triage were scans 10-95 were run. Flats taken this night not used in processing.

CALMON passes all remaining cal sets after triage with no overides. J-band cals were significantly depressed all night (-0.2 mag), H and K were also slightly depressed (~-0.05 mag). Repeatability in the overlaps is fine in the remaining scans, although not all scans have overlap information. http://irsatest.ipac.caltech.edu:8001/data/2mass/lgos/qa990623n/ut990623n.ps http://irsatest.ipac.caltech.edu:8001/data/2mass/lgos/qa990623n/cum990623n.ps In summary, Scans Phot. quality factor ------- -------------------- 016-023 1.0 030-037 1.0 044-050 1.0 057-063 1.0 070-076 1.0 083-089 1.0 Sensitivity: ------------ Sensitivities are not great at k-band, but most of the night survives with scores of 8 or higher (with the exception of the first few scans of the night). The seeing shape is enhanced all night at k-band relative to the other bands. All in all a pretty good northern summer night.
