This model interpolates from a grid of NS atmosphere calculations
provided by George Rybicki and Ramesh Narayan to output a NS
atmosphere spectrum. The model grids cover a wide range of surface
gravity and effective temperature, and incorporate thermal electron
conduction and self-irradiation by photons from the compact
object. This code assumes negligible (less than G) magnetic
fields and a pure hydrogen atmosphere. A detailed description of the
model is given in Heinke et al. (2006)
(see also
McClintock et al. 2004).
