The Difference in Magnitudes from Flux Ratio calculator computes the difference in magnitude (Dm) based on the(r). Two objects have differing intensities as measured by an observer. The ratio of the measured intensities (or "fluxes") is given as "r". These two objects have different astronomical "magnitudes". The difference in their magnitudes is given by this formula.
