980319s [v3] http://2massqa.ipac.caltech.edu:9000/data/2mass/lgos_v3/qa980319s/ Processing notes: ----------------- Scans failing processing: None Minor planet ID's: Asteroid 64 (Angelina) successfully identified. Distortion plots: These look very good. Scan tracking errors: NONE Photometricity: --------------- Calibration strategy: New CALMON overrides: None CALMON passes entire night with nice looking solutions. Overlaps plots show considerable residual biases in the photometric differences. The J-band bias is the worst, reaching ~0.06 mag for the last sci block. The PSF photometry on this night is known to have problems, so this effect will not be investigated in detail unless it appears after new PSFs are generated. At least the PSF sigmas seem to be ok again, and none of the sci blocks gets an overlaps downgrade. In summary, Scans Phot. quality factor ------- -------------------- 007-014 1.0 021-028 1.0 035-042 1.0 049-055 1.0 062-068 1.0 087-094 1.0 101-105 1.0 112-117 1.0 124-129 1.0 136-142 1.0 Backgrounds/Coadds: ------------------- Backgrounds show the Orion Nebula in scans 009-012. Backgrounds appear ratty in scans 136-142 due to high source density. Meteor/artifact removal has done very well. Blanking in the Orion Nebula has not caused an problems, and spot checks of other affected coadds show that the blanking has done a good job of removing real garbage.

(Howard knows of this bug and is working on the fix). Also, the "V2 Deltas" plot does not work off the QA web page. SCANSCI Version 010525 (3.0b6) last run on Sun May 27 23:47:24 2001
