  11. Photo-z’s Polletta et al 2005 ~2.4 million galaxies in SWIRE ==> Photo-z’s are essential: • M. Rowan-Robinson/T.

  21. Photometric redshifts: IMP-z • IMPz (Babbedge et al 2004) colour-tables, which incorporate • (1) integration over filter transmission functions, • (2) correct treatment of IGM, • (3) Berta synthetic seds fitted to Rowan-Robinson (2003) empirical templates • double-pass to cope with AGN dust tori: • Pass 1: don’t use 3.6, 4.5 mu if S(3.6)/Sr > 3 • - then fit ir templates to sources with ir excess at 4.5-160 mu • Pass 2: use 3.6, 4.5 mu provided S(3.6)/Sr <300, unless IR template fit identified source as being dominated by torus • parabolic interpolation of redshift fit to improve accuracy • AV,max = 1.0, MB limits as in RR(2003), minimum errors set in UgriZ,3.6,4.5 = 0.10, 0.03, 0.03, 0.03, 0.10 m., 2.5,4 muJy Extreme Starbursts; LiJiang China
