Photoelectric absorption with variable abundances.
XSpec model.
A photoelectric absorption with variable abundances using
Balucinska-Church and McCammon (ApJ 400, 699) cross-sections set by
the xspecxsect command. The column for each element is in units of
the column in a solar abundance column of an equivalent hydrogen
column density of 10^22 cm^-2. The Solar abundance table used is set
by the xspecabundan command. This model is identical to xsvphabs
except for the way that the parameters are defined.
xsvarabs Parameters
| 1-18 | (element) |
equivalent columns for H, He, C, N, O, Ne, Na, Mg, Al, Si, S,
Cl, Ar, Ca, Cr, Fe, Co, Ni |
