Northern Field (Bootes) 4. 65 deg 2 complete

Southern Field (Cetus) 2. 11 deg 2 complete, 14 nights remaining in Fall 2004

Survey Status • Have imaged 6. 8 sq. degrees with 14 nights remaining • Averaging ~50% usable nights so far • Expect to have ~8 -8. 5 sq. degrees by end of 2004 – Bootes: 4. 65 sq. deg – Cetus: ~3. 5 -4 sq. deg • Data >80% reduced • Initial series of papers planned for summer/fall

Data Products and Data Release • J & Ks merged photometric catalog – SExtractor output – Subarcsecond astrometry • Merged with NDWFS catalog Bootes data release planned for late 2004 Cetus data release planned for spring 2005

The FLAMINGOS Extragalactic Survey: First High-Redshift Cluster Candidates • Preliminary detection using wavelets for J-Ks=1. 75 -2. 5 • Will eventually utilize photo-z’s (BVIJKs)

Summary • The FLAMINGOS Extragalactic Survey is almost complete! – Last observations in fall 2004 – Final area ~8 -8. 5 deg 2 • Complete Bootes data release by late 2004 – Matched J & Ks catalogs – Plan to also release merged catalogs with NDWFS • Key element of the large multiwavelength effort in NDWFS
