Quality Team Report 03/05/07 Source: L492 AOR ID: IRAC: 0005144832, 0005145344 MIPS: 0009419008, 0009420032 Observation Dates: IRAC: 9/2/04, 9/3/04 MIPS: 9/24/04, 9/25/04 Observing Strategy: IRAC: 2 epochs, 1 map of 2 columns & 3 rows, 2 dithers, 12 sec integration per exposure MIPS: 2 epochs, 24: 1 cycle of 3 sec exposures, small field size, 1 map of 1 column & 3 rows 70: 1 cycle of 10 sec exposures, small field size, 1 map of 1 column & 3 rows Processing History (software version): IRAC SSC: S13.2.0 MIPS SSC: S13.2.0 IRAC CC: v2 MIPS CC: v4 IRAC Map1: v11292006 MIPS Map1: v11292006 Map2: v6.6 Comments: Some muxbleed and associated pinstriping, along with column pull-down, from bright stars is present in IRAC bands 1 and 2. Some optical banding around bright stars is present in IRAC bands 3 and 4. ### Catalog Statistics ### # Total Number of sources: 18470 (16128 with epoch 3 detections) 2MASS: 2071 11.2% IRAC1: 10765 58.3% IRAC2: 10054 54.4% IRAC3: 3231 17.5% IRAC4: 1327 7.2% MIPS1: 214 1.2% Number of sources detected in X 2MASS/IRAC/MIPS24 bands: 1 band: 8685 53.9% 2 band: 4350 27.0% 3 band: 1005 6.2% 4 band: 384 2.4% 5 band: 1034 6.4% 6 band: 206 1.3% 7 band: 433 2.7% 8 band: 31 0.2% Sources detected in 3+ bands: 3093 Total IRAC 2MASS: 65 2.1% 9 0.3% Stars: 2742 88.7% 2741 90.3% YSOc : 1 0.0% 1 0.0% Galc : 7 0.2% 7 0.2% Other: 278 9.0% 278 9.2%
