The word "photometric" refers to the measurement and evaluation of light, specifically its intensity and distribution. It is a way to describe and analyze the properties of light, such as brightness or color, using scientific techniques.
The rotation period distributions show a clear mass - dependent morphology, statistical... ▽ More We report on the results of a time - series photometric survey of M50 (NGC 2323), a ~ 130 Myr open cluster, carried out using the CTIO 4m Blanco telescope and Mosaic - II detector as part of the Monitor project.

Access to the AAVSO database of photometric observations is freely available to anyone online and light curves can be generated using the AAVSO light curve generator. (reddots.space)
Ellen Howell (National Astronomy and Ionospheric Centre, NAIC, Arecibo Observatory) and Mikko Kaasalainen (Helsinki University) were provided with photometric data to support radar observations and asteroid shape modeling respectively. (britastro.org)
