The Stellar Abundances and Galactic Evolution Survey:Photonic Passbands and Extinction Coefficients for the u and v Bands
文献摘要：
The Stellar Abundances and Galactic Evolution Survey(SAGES)is a multi-band photometric survey focused on estimation of stellar atmospheric parameters and interstellar extinction.In this paper we have derived photonic passbands for the intermediate-band u and v filters of the SAGES photometric system.The derived photonic passbands have been compared with those of the u and v filters of the Str?mgren and SkyMapper systems.Synthetic photometry based on the derived photonic passbands could reproduce the observations very well.We have also derived observed,model-free extinction coefficients for the SAGES u and v bands(as well as the Pan-STARRS grizy bands)using the"standard pair"method.The derived reddening coefficients have been compared with those predicted by the extinction laws.Variations of reddening coefficients with effective temperatures and color excesses of B-V given by Schlegel et al.(E(B-V)SFD)have been investigated.No obvious trends or significant variations with effective temperatures have been found,but reddening coefficients for all the colors exhibit declining trends with increasing E(B-V)SFD,with typical relative variations of twenty-some percent from E(B-V)SFD～0 to 1.
