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, $M_{BH}$-${\chi }_{red}^2$ variation from TCAF fits. We find a mass range of $4.06-7.93M_{\odot }$ with a most probable value at $6\pm 2M_{\odot }$.
