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.

WebPhotometric system. 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. http://hea.iki.rssi.ru/AZT22/RUS/eaa_bessel.pdf

Webmagnitudes are estimates based on observations made in wider bands, and the conversion to flux can only be as good as broader-band observations can be calibrated. In fact, these systems are the stepchildren of more basic broad-band systems in use by astronomers for over 100 years—but which are more awkward in definition and usage. II.
