The Brightest Cluster Galaxies properties of SPIDERS X-ray galaxy clusters

We provide the brightest cluster galaxies (BCGs) catalog for the SPIDERS DR14 X-ray detected galaxy clusters VAC. This catalog lists the BCGs identified as part of this process, along with their stellar mass, star formation rates (SFR), and morphological properties. BCGs are identified based on the available spectroscopic data from SPIDERS and photometric data from SDSS (Erfanianfar et al. in prep). Only those SPIDERS clusters which have one component in the SPIDERS X-ray galaxy clusters are considered in this analysis. Stellar masses and SFRs of the BCGs are computed by combining SDSS, WISE and GALEX photometry, and using state-of-the-art spectral energy distribution (SED) fitting. Where available, the star formation rate is taken from the MPA-JHU galaxies properties VAC instead of from the SED fitting. The morphology properties (effective radius, Sersic index, axis ratio, integrated magnitude and reduced χ² for the frame) for all BCGs are provided by Sersic profile fitting using SIGMA (Kelvin et al. 2012) in different optical bands (g,r,i). Three models are provided, in three bands: Free Sersic (n=1-20, S), Free Sersic + Exponential (n=1-20 + n=1, SX) and De Vaucouleurs (n=4, V) (Furnell et al. in prep).
