calculating fluxes and errors
Prompted by a question from Jeremy Sanders I have developed a new way of calculating fluxes and errors for models and parts of models. The trick is to provide a new convolution model called cflux whose first two parameters are the minimum and maximum energy over which the flux is calculated. The final parameter is the flux. The component is placed in front of the model component(s) whose flux is being calculated and one of the additive components has its normalization frozen. The standard fit and error command on the flux parameter will then provide the best fit flux and confidence region. This model is available through the extra models web page.
