(erg/s/cm2) [keV] ArmasPadilla2013
Outburst magnitude (AB) r'=16.3±0.05 (mag) Rau2011
Quiescent magnitude (AB) r'=21.71±0.08 (mag) Shahbaz2013 ArmasPadilla2014a MataSanchez2015 Shahbaz2013

Notes Swift J1357.2-0933 in rigour is not a dynamical BHT because it lacks a detection of the secondary star but it has a robust mass function determination ( Corral-Santana2013 , MataSanchez2015 ). The distance is still uncertain (see Rau2011 , Shahbaz2013 , MataSanchez2015 ).
