Effective-temperature estimates, T_eff, from SPHINX, as a function of the adopted value from the SSPP for a testing catalog consisting of J-PLUS EDR photometry (left panels). For comparison, g– r calibrations from Fukugita et al. (2011; middle panels) and Lee et al. (2008a; right panels) were applied to the sample. The residuals for each temperature calibration are shown against the accepted temperature in the bottom panels, where the green region depicts the standard deviation from a Gaussian maximum-likelihood fit.
