Enumeration Type Documentation

enum pmSourcePhotometryMode

The function returns both the magnitude of the fit, defined as -2.5log(flux), where the flux is integrated under the model, theoretically from a radius of 0 to infinity. In practice, we integrate the model beyond 50sigma. The aperture magnitude is defined as -2.5log(flux) , where the flux is summed for all pixels which are not excluded by the aperture mask. The model flux is calculated by calling the model-specific function provided by pmModelFlux_GetFunction. XXX: must code this.
