Notes. (a) The errorbars were scaled so 
for each individual dataset before performing the joint fit. (b)
The best-fit values of T14
and b differ significantly between MASCARA and the joint fit. This difference most likely originates from the algorithms used to calibrate the MASCARA data, which are known to potentially modify the transit shape.
