Estimated astrometric and photometric accuracy for the three data sets when compared to the HST ACS F775W image.
Data set | AB < 25 | 25 < AB < 27 | 27 < AB |
---|---|---|---|
Average astrometric offsets (arcsec) | |||
MXDF | 0.12 ± 0.04 | 0.13 ± 0.05 | 0.13 ± 0.06 |
UDF10 | 0.08 ± 0.02 | 0.10 ± 0.05 | 0.15 ± 0.09 |
MOSAIC | 0.05 ± 0.02 | 0.08 ± 0.05 | 0.16 ± 0.10 |
Average AB magnitude differences | |||
MXDF | 0.08 ± 0.04 | 0.09 ± 0.07 | 0.25 ± 0.19 |
UDF10 | 0.07 ± 0.04 | 0.23 ± 0.13 | 0.35 ± 0.24 |
MOSAIC | 0.10 ± 0.08 | 0.24 ± 0.16 | 0.32 ± 0.23 |
Notes. Mean and standard deviation are given for three AB magnitude intervals. The mean AB magnitude error reported by SExtractor for the HST convolved image amounts to 0.002, 0.011 and 0.030 in the AB < 25, 25 < AB < 27 and AB > 27 intervals, respectively.
