The calibrations are based on data for 16 early-type galaxies in the Virgo and Fornax clusters observed with WFC3/IR and are provided as functions of both the optical (g-z) and near-infrared (J-H) colors. The scatter about the linear calibration relations for the luminous red galaxies in the sample is approximately 0.10 mag, corresponding to a statistical error of 5% ","authors_text":"(2) NRC Herzberg Astrophysics, (3) The University of Texas Rio Grande Valley, (4) INAF-Osservatorio Astronomico di Teramo, (5) Brigham Young University, (6) Yonsei University), Gabriella Raimondo (4), Hyejeon Cho (6) ((1) Utah Valley University, Hyun-chul Lee (3), John P.
