Quality Team Report 03/02/2007 Source: Chamaeleon II AOR ID: IRAC: 0005739520, 0005739776, 0005740032, 0005740288, 0005740544, 0005740800 MIPS: 0005741056, 0005744640, 0005744896, 0005745152 IRAC off-cloud: 0005741312, 0005741568, 0005741824, 0005742080, 0005742336, 0005742592 Observation Dates: IRAC: 2004-04-04 MIPS: 2004-04-06 Observing Strategy: IRAC: 2 epochs, 2 dithers, 12 sec integration per exposure one epoch in HDR mode, one epoch of full array MIPS: fast scan map, 2 epochs 125" cross-scan, 80" in-scan offset between epochs Processing History (software version): IRAC SSC: S13.2.0 MIPS SSC: S13.2.0 IRAC CC: 2 MIPS CC: 4 IRAC Map1: v11292006 MIPS Map1: v11292006 Map2: 6.6 Comments: Mysterious bright patch seen in the 24-micron ChamII-2 BCD and removed by hand in the ICD data Significant muxbleed and associated pinstriping, along with column pull-down, from bright stars is present in IRAC bands 1 and 2. Optical banding around bright stars is present in IRAC bands 3 and 4. Latent images from bright sources are not fully removed from the MIPS images. False detections associated with these latent images have been removed from the band-merged source catalog. ### Catalog Statistics ### # Total Number of sources: 265607 (198395 with epoch 3 detections) 2MASS: 41364 15.6% IRAC1: 115269 43.4% IRAC2: 105002 39.5% IRAC3: 44715 16.8% IRAC4: 14935 5.6% MIPS1: 2782 1.0% Number of sources detected in X 2MASS/IRAC/MIPS24 bands: 1 band: 95453 48.1% 2 band: 54990 27.7% 3 band: 30068 15.2% 4 band: 3423 1.7% 5 band: 4738 2.4% 6 band: 2450 1.2% 7 band: 6949 3.5% 8 band: 324 0.2% Sources detected in 3+ bands: 47952 Total IRAC 2MASS: 19631 40.9% 16 0.1% Stars: 22958 47.9% 22698 81.0% YSOc : 29 0.1% 29 0.1% Galc : 298 0.6% 298 1.1% Other: 5036 10.5% 4966 17.7%
