Photometric passband b
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).

Web2.2 Passband Evaluation For any given photometric system, synthetic photometry should first be used to establish that the observed photometric data are consistent with the observed spec trophotometry data of the stars. It is imperative to determine those passband functions, P,(A), which yield synthetic magnitudes matching the observed ones, for Webbol; and L are the absolute bolometric magnitude and luminosity of the Sun, respectively. The BCvalues are highly dependent on both a) the photometric passband used to carry out the observations, and b) the underlying stellar spectrum for which the correction has to be carried out. We represent the passband dependence through the subscript
