vmshift: velocity shift a multiplicative model

This convolution model velocity shifts a multiplicative model. It takes the
calculated model and shifts energies by .

The energies command must be to used to extend the energy range
over which the model is being calculated.

The parameter is:

par1= |
velocity (km/s) |

An example model use is:

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

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