The XSPEC vbremss model: thermal bremsstrahlung.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The HeH parameter has been renamed HeovrH to match the XSPEC definition. The name HeH can still be used to access the parameter, but this name will be removed in a future release.

kT

HeovrH

The ratio n(He) / n(H).
