Abell 1689. Our map of Abell 1689 exhibits a great deal of extended submm
emission around the expected centroid of SZ effect emission, which is best
explained as a submm image of the cluster's SZ effect. This cluster has been a
very popular target for SZ effect measurements, including SuZIE II (Benson et
al. 2004) and OVRO/BIMA at the SZ decrement (Holzapfel et al. 1997; Grego et al.
2001; Reese et al. 2002; LaRoque et al. 2006). Cooray et al. (1998) discuss
point sources at 30 GHz.
A1689. This cluster has no clear evidence of soft excess emission.
