Estimation of mass of MAXI J1659-152 during its very first outburst with TCAF fits

We determine mass of MAXI J1659-152 using two different methods, viz: constant Normalization parameter point of view while fitting with TCAF, $M_{BH}$-$\chi^2_{red}$ variation from TCAF fits. We find a mass range of $4.06-7.93~M_\odot$ with a most probable value at $6 \pm 2 M_\odot$.
