Notes. The 1σ error bars are the internal errors after deconvolution. Additional 2-mas systematic errors must be added to these (see text). The magnitudes are in the Vega system. For comparison we show the results from Morgan et al. (2005) using HST/ACS images and from Kochanek et al. (2006) using HST/NIC2 images.
