Photometric redshifts for quasars from WISE-PS1-STRM

Photometric redshift estimations for quasars In this repository we publish our photometric redshift catalogue of quasar candidates found in the cross-matched catalogue of the WISE All-Sky and PS1 3π DR2 sky surveys. Altogether there are 4,849,607 quasars in the catalog from which 2,879,273 are covered by our training set. When using this data please cite our work

Below you can find the description of each column: objID_PS1: object id in the PanSTARRS DR2 catalogue raMean: rectascension of the object decMean: declination of the object w1mpro: PSF profile-fitting magnitude measured in WISE W1 filter w1sigmpro: error estimation of w1mpro w1mag: aperture magnitude related to 8.25" radius circular apertures measured in WISE W1 filter w1sigm: error estimation of w1mag w2mpro: PSF profile-fitting magnitude measured in WISE W2 filter w2sigmpro: error estimation of w2mpro w2mag: aperture magnitude related to 8.25" radius circular apertures measured in WISE W2 filter w2sigm: error estimation of w2mag gFPSFMag: PSF profile-fitting magnitude measured in PS1 g filter gFPSFMagErr: error estimation of gFPSFMag rFPSFMag: PSF profile-fitting magnitude measured in PS1 r filter rFPSFMagErr: error estimation of rFPSFMag iFPSFMag: PSF profile-fitting magnitude measured in PS1 i filter iFPSFMagErr: error estimation of iFPSFMag zFPSFMag: PSF profile-fitting magnitude measured in PS1 z filter zFPSFMagErr: error estimation of zFPSFMag yFPSFMag: PSF profile-fitting magnitude measured in PS1 y filter yFPSFMagErr: error estimation of yFPSFMag gFKronMag: Kron magnitude measured in PS1 g filter gFKronMagErr: error estimation of gFKronMag rFKronMag: Kron magnitude measured in PS1 r filter rFKronMagErr: error estimation of rFKronMag iFKronMag: Kron magnitude measured in PS1 i filter iFKronMagErr: error estimation of iFKronMag zFKronMag: Kron magnitude measured in PS1 z filter zFKronMagErr: error estimation of zFKronMag yFKronMag: Kron magnitude measured in PS1 y filter yFKronMagErr: error estimation of yFKronMag EBV_PS1: E(B-V) dust extinction values EXT: flag denoting an object being extrapolated or not in the 12-dimensional color index space. It is 1 if the object is extrapolated and 0 if not. DIST: average distance measured between the inference data points and their spectroscopic neighbors in the 12-dimensional color index space. z_pred: photometric redshift estimation (predicted from color indices) z_pred_std: uncertainty of z_pred spectroz: spectroscopic redshift of the object if available and -999 otherwise EXT2: flag denoting an object being extrapolated or not in the 13-dimensional color index+magnitude space. It is 1 if the object is extrapolated and 0 if not. DIST2: average distance measured between the inference data points and their spectroscopic neighbors in the 13-dimensional color index+magnitude space. z_pred2: photometric redshift estimation (predicted from color indices+magnitude) z_pred_std2: uncertainty of z_pred2
