To da te\, the low mass end of this sequence is best mea sured at the highest redshifts with Hubble+Spitzer photometry\, with ground-based K-band data to bri dge the gap. We revisit the measurement of this re lation from the Hubble Frontier Fields using BEAGL E\, a Bayesian SED fitting code (Chevallard & Char lot 2016)\, to compute the posterior mass\, SFR an d redshift for main sequence galaxies spanning cos mic time. Our Bayesian hierarchical model of the m ain sequence (an extension of the work of Curtis-L ake et al. 2021) self-consistently propagates unce rtainties on mass\, SFR and redshift estimates to uncertainties on the main sequence parameters\, wh ilst explicitly accounting for potential main sequ ence outliers. In this study we measure the main s equence relation between 1
