KY Relativistic Accretion Disk Models
Original language description
We have developed a new ray-tracing routine that enhances capabilities to model the emission line profiles from black-hole accretion discs. The new routine, "ky", cooperates with XSPEC. It is supposed to be more accurate and versatile than laor (Laor 1991), and faster than kerrspec (Martocchia et al. 2000). Among other features, ky allows to fit various parameters such as black hole angular momentum, observer inclination, an accretion disc size, etc. It also allows to change the grid resolution and, hence, to control accuracy and computational speed. There is an option to explore time variable sources.
