VizieR Online Data Catalog: HST observations of Extremely Red Objects (Smith+, 2002)

We present the results of a survey for extremely red objects (EROs) undertaken in the fields of 10 massive galaxy cluster lenses at z~0.2, combining sensitive, high-resolution Hubble Space Telescope imaging with deep, half-arcsecond K-band imaging from UKIRT. We detect 60 EROs with (R-K)>=5.3, of which 26 have (R-K)>=6.0 in a total image-plane survey area of 49arcmin2 down to K=20.6, including one multiply imaged ERO.
