Stellar mass and age analysis of WASP-127 (upper panel), WASP-136 (middle panel) and WASP-138 (lower panel) using BAGEMASS. The dotted black line is the ZAMS. The solid blue line is the mass evolutionary track, and the blue dashed tracks on either side are for the 1σ error of the mass. The solid orange line is the stellar age isochrone and the orange dashed lines represents the 1σ error. The density of MCMC samples is shown in the colour scale of the plotted posterior distribution.
