Table C.1.

Benchmarks {A,B}2 and {A,B}3 with getsf and getold in the standard approach, with all seven images combined for source detection. The extraction qualities, defined in Eqs. (2)–(6), are evaluated for only acceptable sources, cf. Eq. (1), with errors in measurements within a factor of 21/2. The numbers of model sources are NT = 459 in Benchmark A and NT = 919 in Benchmark B. Source measurements in the image of derived surface densities are known to be inaccurate (e.g., Appendix A of Paper I), hence the data are not presented.
