The effect of the object magnitude at a specific observation band

For all the previous input flux distributions the intensity is rescaled according to the object magnitude and the observing band set by the user from the interface.

The following table provides the photometric zero points (Vega system) and links to the broad-band filter curves used in the magnitude calculations.

Band Filter curve Photometric zeropoint in ergs/s/cm2/A
(flux for zero mag in Vega system)
U U filter curve U0 = 4.18023e-09
