27 April 2004 README - IRAC - Extragalactic First-Look Survey The Extragalactic First-Look Survey (XFLS) spent 62.5 hours with IRAC and MIPS mapping a 4 square degree region near the ecliptic pole. The IRAC observations for the main survey have ~60 seconds of integration time per pixel. A ~0.2 square degree verification survey was done within the main field with an exposure time of 600 seconds per pixel. The main survey is centered at J1718+5930 and the verification survey is centered at J1717+5945. --------------------------------------------------- Log of IRAC Observations --------------------------------------------------- AOR Label AOR-ID AOR Execution Start Duration Date/Time (minutes) (UTC) --------------------------------------------------- MAIN SURVEY: FLS-IRAC-main1 3861504 144.23 2003-12-01 15:28:23.6 FLS-IRAC-main2 3861760 164.39 2003-12-01 17:41:03.5 FLS-IRAC-main3 3862016 146.44 2003-12-02 04:52:34.1 FLS-IRAC-main4 3862272 164.33 2003-12-02 17:48:43.5 FLS-IRAC-main5 3862528 184.53 2003-12-03 00:02:45.0 FLS-IRAC-main6 3862784 184.63 2003-12-03 05:43:19.6 FLS-IRAC-main7 3863040 144.25 2003-12-03 14:16:03.8 FLS-IRAC-main8 3863296 184.55 2003-12-04 03:16:13.4 FLS-IRAC-main9 3863552 182.34 2003-12-04 06:06:36.1 VERIFICATION SURVEY: FLS-IRAC-ver1a 7677184 30.06 2003-12-05 13:24:50.2 FLS-IRAC-ver1 3866880 65.90 2003-12-05 13:50:55.8 FLS-IRAC-ver1b 7676928 30.06 2003-12-05 14:50:30.5 FLS-IRAC-ver3 3867392 117.09 2003-12-05 15:16:41.5 FLS-IRAC-ver2 3867136 231.05 2003-12-05 17:06:55.4 FLS-IRAC-ver4 3867648 117.08 2003-12-06 01:29:27.8 ---------------------------------------------------
