WebFor example, direct imaging of extra-solar planets offers limited light, making photometry more practical than spectroscopy. Some subtypes of photometry: broad band photometry - passband width on the order of 100 nm. intermediate band photometry - on the order of 20 nm. narrow band photometry - on the order of 5 nm. WebIn UBVRI photometry portions of a star’s spectrum are selected using optical filters. For such broad-band photometry the resulting passbands have a full-width half maximum (FWHM) ~ 100 nm (Majewski 2008).

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.
