## Subset of objects corresponding to 252.html ## ## RELICS: Reionization Lensing Cluster Survey ## Cycle 23 Hubble Treasury program (GO 14096; PI Coe) ## http://relics.stsci.edu ## ## plckg138-10-par HST source catalog ## Photometric + Bayesian Photometric Redshift (BPZ) catalog (produced 2018-10-09 by Dan Coe) ## based on drizzled 0.06"/pix images (produced 2016-06-07 by Roberto Avila and Sara Ogaz) ## HST observation plan (Phase 2) by Larry Bradley ## HST program coordinated by Bill Januszewski ## ## 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 2.8.6) in a weighted sum of WFC3/IR images ## Not pruned: a few < 5-sigma detections may remain ## 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) = 0.19020 ## 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 and template are given by zb and tb, ## and the 95% confidence range is given by zbmin - zbmax. ## The templates used here are 5 ellipticals (1-5), 2 spirals (6-7), and 4 starburst galaxies (8-11). ## Higher values of tb generally correspond to bluer templates. ## Here we use the origninal Bayesian prior P(z,t | mag) derived from the HDFN (Benitez 2000). ## This prior is less conservative with regard to high redshifts ## than some updated priors used in later works (Benitez+09, Coe+13). ## 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. ## The "maximum likelihood" (flat prior) redshift zml and type tml are also reported. # 1 id Object ID Number # 2 RA Right Ascension in decimal degrees # 3 Dec Declination in decimal degrees # 4 x x pixel coordinate # 5 y y pixel coordinate # 6 fwhm Full width at half maximum (arcsec) # 7 area Isophotal aperture area (pixels) # 8 stel SExtractor "stellarity" (1 = star;
