Abstract: We present progress results from the Fastsum collaboration’s programme to determine the spectrum of the bottomonium system as a function of temperature using a variety of approaches. Inthese proceedings, the Maximum Likelihood approach is used with an Ansatz comprising of a Gaussian spectral function for the ground state. Fastsum anisotropic lattices with 2 + 1 dynamicalquark flavours were used with temperatures ranging from 47 to 375 MeV.
