## Subset of objects corresponding to 766.html ## ## RELICS: Reionization Lensing Cluster Survey - Cycle 23 Hubble Treasury program (GO 14096; PI Coe) ## Photometric + Bayesian Photometric Redshift (BPZ) catalog (produced 2016-04-20 by Dan Coe) ## from 0.06"/pix images of rxc0911+17 (produced 2016-04-19) ## by Roberto Avila and Sara Ogaz (STScI) ## ## Note: photo-z estimates are intended for galaxies only ## Stars may be identified as having higher values of SExtracor stellarity ## ## Objects detected by SExtractor (version 2.19.5) in a weighted sum of ACS+IR images ## Pruned by selecting flag5sig = 0 (gets rid of cosmic rays and < 5-sigma detections) ## Position, aperture, and shape measurements determined in the detection image ## ## Photometry measured in isophotal apertures by SExtractor in dual-image mode ## For each filter, we provide: ## - AB magnitude & uncertainty ## - flux & uncertainty (electrons / second = native units) ## - flux & uncertainty (nJy = nanoJanskys) ## - detection significance ## - zeropoints to convert native fluxes (e-/s) to AB magnitudes ## ## AB mag = zeropoint - 2.5 * log10(flux) = 31.4 - 2.5 * log10(fluxnJy) ## Magnitude uncertainties correspond to the flux 1-sigma upper limits: ## magerr = 2.5 * log10(1 + fluxerr / flux) ## ## Both fluxes and magnitudes have been corrected for ## galactic extinction: E(B-V) = 0.03590 ## based on Schlafly & Finkbeiner 2011 (ApJ 737, 103) ## extracted using http://irsa.ipac.caltech.edu/applications/DUST/docs/dustProgramInterface.html ## ## mag, magerr = 99, 1-sigma limit: non-detection (flux < 0) ## mag, magerr = -99, 0: unobserved (outside FOV, in chip gap, etc.) ## ## For each object, we also provide the brightest magnitude in any filter ## based on the highest observed flux - fluxerr (lower limit) ## ## Bayesian Photometric Redshifts are derived using BPZ (Benitez et al. 2000, 2004; Coe et al. 2006) ## These results are intended for galaxies only. ## (Stars may be pruned as having higher values of SExtractor stellarity.) ## For each object, the most likely redshift is given by zb, ## and the 95% confidence range is given by zbmin - zbmax. ## Objects with high ODDS values have sharply peaked unimodal redshift likelihood distributions. ## Objects with chisq2 < 1 generally have photometry well fit by the model SEDs. #
