Rereduced HST Imaging in EGS

These mosaics have been produced following similar procedures to those described in Koekemoer et al. (2011, ApJS, 197, 36), in particular incorporating improvements in calibration and astrometry beyond those available from the default HST archive pipeline products. The absolute astrometric frame for these mosaics is Gaia-EDR3, and all the mosaics are pixel aligned to each other on this astrometric frame to a precision of a few milliarcseconds. The mosaics combine data in 6 filters (ACS/WFC F606W, F814W and WFC3/IR F105W, F125W, F140W, F160W) from a total of 1,767 exposures, obtained from eight different HST programs (10134, 12063, 12099, 12167, 12177, 12547, 13063, 13792), with all the mosaics at a pixel scale of 30 milliarcseconds/pixel. For any projects that make use of these mosaics or products derived from them, please cite Koekemoer et al. (2011, ApJS, 197, 36)
