In theory:
2)
Computing atmospheric models at different magnetic
inclinations
1)
Assuming B-field topology and computing surface temperature
profile
3)
Ray-tracing in the strong gravitational field.

4)
Predicting:
a) lc
and b) spin

of the line parameters!
GOAL: probe the surface
properties of the NS via timing and pulse-phase spectroscopy of cyclotron lines!
