In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation. The sensitivity usually depends on the optical system, detectors and filters used. For each photometric system a set of primary standard stars is provided. A commonly adopted … See more Each letter designates a section of light of the electromagnetic spectrum; these cover well the consecutive major groups, near-ultraviolet (NUV), visible light (centered on the V band), near-infrared (NIR) and part of mid-infrared (MIR).

We calculate the new photometry for the rest of the Johnson optical and the Bessell infrared filters. We calculate extinction A =Δm A = Δ m and plot color excess, E(λ−V)= Aλ −AV E ( λ − V) = A λ − A V.
