ezdiskbb: multiple blackbody disk model with zero-torque
inner boundary

A multi-temperature blackbody model for a thin, steady-state,
Newtonian accretion disk, assuming zero torque at the inner boundary
for the disk at radius . The temperature of the disk as a function
of radius is assumed to be
,
where and
. The maximum temperature in the disk is given
by
.

This model is an alternative to diskbb, which assumes a non-zero
torque at the inner edge and a temperature profile
, and it should be used to fit spectra of disks when the
zero-torque inner boundary condition is appropriate. For details see
Zimmerman et al. (2004) astro-ph/0408209.
