This convolution model redshifts a multiplicative model. It takes the calculated model and shifts energies by 1/(1+z).

The energies command must be to used to extend the maximum energy over which the model is being calculated to (1+z) times the maximum energy in the response.

The parameter is:

An example model use is:

XSPEC> model phabs * (zmshift*phabs) * pow

which multiplies the power-law by both a redshifted and local absorption.
