## Subset of objects corresponding to 183.html ## ## RELICS: Reionization Lensing Cluster Survey - Cycle 23 Hubble Treasury program (GO 14096; PI Coe) ## Photometric + Bayesian Photometric Redshift (BPZ) catalog (produced 2016-05-27 by Dan Coe) ## from 0.06"/pix images of abell1758 (produced 2016-05-27) ## 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 IR images ## Not pruned: a few < 5-sigma detections may remain (flagsig > 0) ## 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) = 0.01220 ## 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. # 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; 0 = galaxy) # 9 ell Ellipticity = 1 - B/A # 10 flag5sig 0 = probably real; 1 = probable CR; 2 = no 5-sigma detection # 11 nf5sig Number of filters with a 5-sigma detection # 12 nfcr5sig Number of CR-vulnerable filters with a 5-sigma detection # 13 nfobs Number of filters observed (not in chip gap, etc.) # 14 f435w_mag F435W isophotal magnitude (ZP = 25.6656) # 15 f435w_magerr F435W isophotal magnitude uncertainty (Edges vulnerable to cosmic rays) # 16 f435w_flux F435W isophotal flux (multiplied by 1.047 to correct for extinction (-0.050 mag)) # 17 f435w_fluxerr F435W isophotal flux uncertainty (1.047 factor applied here as well) # 18 f435w_fluxnJy F435W isophotal flux in nJy (multiplied by 1.047 to correct for extinction (-0.050 mag)) # 19 f435w_fluxnJyerr F435W isophotal flux in nJy uncertainty (1.047 factor applied here as well) # 20 f435w_sig F435W detection significance # 21 f606w_mag F606W isophotal magnitude (ZP = 26.4934) # 22 f606w_magerr F606W isophotal magnitude uncertainty (Edges vulnerable to cosmic rays) # 23 f606w_flux F606W isophotal flux (multiplied by 1.033 to correct for extinction (-0.036 mag)) # 24 f606w_fluxerr F606W isophotal flux uncertainty (1.033 factor applied here as well) # 25 f606w_fluxnJy F606W isophotal flux in nJy (multiplied by 1.033 to correct for extinction (-0.036 mag)) # 26 f606w_fluxnJyerr F606W isophotal flux in nJy uncertainty (1.033 factor applied here as well) # 27 f606w_sig F606W detection significance # 28 f814w_mag F814W isophotal magnitude (ZP = 25.9467) # 29 f814w_magerr F814W isophotal magnitude uncertainty (Edges vulnerable to cosmic rays) # 30 f814w_flux F814W isophotal flux (multiplied by 1.021 to correct for extinction (-0.022 mag)) # 31 f814w_fluxerr F814W isophotal flux uncertainty (1.021 factor applied here as well) # 32 f814w_fluxnJy F814W isophotal flux in nJy (multiplied by 1.021 to correct for extinction (-0.022 mag)) # 33 f814w_fluxnJyerr F814W isophotal flux in nJy uncertainty (1.021 factor applied here as well) # 34 f814w_sig F814W detection significance # 35 f105w_mag F105W isophotal magnitude (ZP = 26.2689) # 36 f105w_magerr F105W isophotal magnitude uncertainty # 37 f105w_flux F105W isophotal flux (multiplied by 1.011 to correct for extinction (-0.012 mag)) # 38 f105w_fluxerr F105W isophotal flux uncertainty (1.011 factor applied here as well) # 39 f105w_fluxnJy F105W isophotal flux in nJy (multiplied by 1.011 to correct for extinction (-0.012 mag)) # 40 f105w_fluxnJyerr F105W isophotal flux in nJy uncertainty (1.011 factor applied here as well) # 41 f105w_sig F105W detection significance # 42 f125w_mag F125W isophotal magnitude (ZP = 26.2303) # 43 f125w_magerr F125W isophotal magnitude uncertainty # 44 f125w_flux F125W isophotal flux (multiplied by 1.009 to correct for extinction (-0.009 mag)) # 45 f125w_fluxerr F125W isophotal flux uncertainty (1.009 factor applied here as well) # 46 f125w_fluxnJy F125W isophotal flux in nJy (multiplied by 1.009 to correct for extinction (-0.009 mag)) # 47 f125w_fluxnJyerr F125W isophotal flux in nJy uncertainty (1.009 factor applied here as well) # 48 f125w_sig F125W detection significance # 49 f140w_mag F140W isophotal magnitude (ZP = 26.4524) # 50 f140w_magerr F140W isophotal magnitude uncertainty # 51 f140w_flux F140W isophotal flux (multiplied by 1.007 to correct for extinction (-0.007 mag)) # 52 f140w_fluxerr F140W isophotal flux uncertainty (1.007 factor applied here as well) # 53 f140w_fluxnJy F140W isophotal flux in nJy (multiplied by 1.007 to correct for extinction (-0.007 mag)) # 54 f140w_fluxnJyerr F140W isophotal flux in nJy uncertainty (1.007 factor applied here as well) # 55 f140w_sig F140W detection significance # 56 f160w_mag F160W isophotal magnitude (ZP = 25.9463) # 57 f160w_magerr F160W isophotal magnitude uncertainty # 58 f160w_flux F160W isophotal flux (multiplied by 1.005 to correct for extinction (-0.006 mag)) # 59 f160w_fluxerr F160W isophotal flux uncertainty (1.005 factor applied here as well) # 60 f160w_fluxnJy F160W isophotal flux in nJy (multiplied by 1.005 to correct for extinction (-0.006 mag)) # 61 f160w_fluxnJyerr F160W isophotal flux in nJy uncertainty (1.005 factor applied here as well) # 62 f160w_sig F160W detection significance # 63 bright_mag Brightest magnitude in any filter # 64 bright_magerr Brightest magnitude uncertainty # 65 zb # 66 zbmin # 67 zbmax # 68 tb # 69 odds # 70 zml # 71 tml # 72 chisq # 73 M0 Magnitude used for BPZ prior: F814W or closest observed filter # 74 chisq2 # 75 nfdet ##
