wndabs, zwndabs: photo-electric absorption, warm absorber
Photo-electric absorption from approximation to a warm absorber using Balucinska,-Church, and McCammon (ApJ 400, 699) cross-sections. Relative abundances are set by the abund command.

where s(E) is the photo-electric cross-section (NOT including Thomson
scattering) and
par1= nH |
equivalent hydrogen column (in units of 1022 atoms cm–2) |
par2= EW |
window energy (keV) |
The zwndabs variant allows the user to specify a (fixed) redshift and uses the corresponding formula:
|
|
1 E > EW |
with parameters:
par1= nH |
equivalent hydrogen column (in units of 1022 atoms cm–2) |
par2= EW |
window energy (keV) |
par3= z |
redshift |
