Strictly speaking it is not a dynamical BH but there is either a robust mass function or mass determination suggesting the presence of a BH

NOTES

MAXI J1659-152: Strictly speaking is not a dynamical BH because it lacks a detection of the secondary star. However, the FWHM(Hα) scaling from Casares2015 coupled with knowledge of the orbital period (Kuulkers2013,Corral-Santana2018) strongly indicates so. In addition, Yamaoka2012 also suggested a BH from the study of X-ray spectral and timing properties. This values should be taken with caution.
