Astrophysics Bachelors Data #1128

Hi,

I'm currently a university student doing physics with astrophysics, my bachelor's project is on lightcurves around TrEs-3 and its planet, I am wondering if there is any radial velocity data for the mass that was obtained in the XML code, I've searched all over and i haven't been able to find a method to obtain the mass of the planet, I thought since it can only be acquired through the radial velocity method, and the number of papers on the planet and even NASA showing the mass, there would be some way of obtaining the method to get it myself, but i've came up unlucky. Would someone be able to explain how this mass was obtained and if there's a way to use this inside Python (jupyter notebook).

The mass was indeed measured by radial velocity; Sozzetti et al. 2009 seems to be the source for the mass value in OEC.
