DESCRIPTION:Hubble data has given us the first estimates of the intrinsic 
 scatter of the main sequence of star-forming galaxies at redshifts >~3.5 (
 Salmon+15).  In fact\, Santini+17 find tentative evidence for increasing s
 catter to low stellar masses\, which may indicate more stochastic star for
 mation.  However\, significant broad-band flux contamination by emission l
 ines\, as well as sparse sampling of galaxy SEDs makes physical parameter 
 estimation uncertain\, and robust treatment of the uncertainties is key.  
 Using Bayesian Hierarchical modelling teamed with the sophisticated nebula
 r modelling of Gutkin+16 and SED-fitting using BEAGLE (Chevallard+16)\, I 
 test the recovery of main-sequence parameters under standard assumptions u
 sed to analyse high redshift data\, and discuss the implications for futur
 e constraints possible with JWST.
