Quality Team Report 02/25/07 Source: L1521B-2 AOR ID: IRAC: 0005074688, 0005075200 MIPS: 0009426432, 0009422848 Observation Dates: IRAC: 10/5/04, 10/7/04 MIPS: 9/19/04, 9/22/04 Observing Strategy: IRAC: 2 epochs, 2 dithers each, 12 sec integration per exposure MIPS: 2 epochs, 24: 1 cycle of 3 sec exposures, large field size 70: 1 cycle of 10 sec exposures, large field size 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: Images: IRAC 1-4 in S13, no strong sources, elongated feature in all bands near center. MIPS 1-2, both filtered and unfiltered. Also shows elongated feature. Source counts, classes, plots look OK.
