+ A. Koekemoer, G. Hasinger, J. Aguirre, J. Schlaerth ...
based on observations with IRAM 30m:
117 channels, 1.2mm ( GHz), 11” FWHM, 4’ FoV
in 2003/ /05, total of 78hr on-sky
90h allocation in winter 2005/6, 55h on sky, 30h useful, but
not included in published data.
Application for 2006/07: 60h
Status: arcmin2 : s < 2 mJy
250 arcmin2 : s < 1 mJy
Aim: 20x20 arcmin2 to < 1 mJy
25x to <1.5 mJy.
Detect: 15 sources S/N > 4
10 sources S/N < 4 but radio source.
