The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

vvoigtabs, zvvoigtabs: voigt absorption line with widths in km/s

A voigt absorption line with line widths in km/s as a multiplicative model. The zvvoigtabs variant includes redshift as a parameter.

$\displaystyle M(E) = exp(-d*v(E)) $

where $v(E)$ is the voigt line shape (see vvoigt for details), and the parameters are:

par1 $E_l$, line energy in keV.
par2 $\sigma$, gaussian line width (sigma) in km/s.
par3 $\gamma$, lorentz line width (FWHM) in km/s.
par4 $d$, line depth in keV.

For zvvoigtabs the parameters are:

par1 $E_l$, line energy in keV.
par2 $\sigma$, gaussian line width (sigma) in km/s.
par3 $\gamma$, lorentz line width (FWHM) in km/s.
par4 $d$, line depth in keV.
par5 $z$, redshift
