  1. Photometry (astronomy) - Wikipedia

    • In astronomy, photometry, from Greek photo- ("light") and -metry ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric ph… See more

    Methods

    Astronomy was among the earliest applications of photometry. Modern photometers use specialised standard

    Magnitudes and colour indices

    Modern photometric methods define magnitudes and colours of astronomical objects using electronic photometers viewed through standard coloured bandpass filters. This differs from other expression… See more

    Applications

    There are many astronomical applications used with photometric systems. Photometric measurements can be combined with the inverse-square law to determine the luminosity of an object if its distance can … See more

    CCD photometry

    A CCD (charge-coupled device) camera is essentially a grid of photometers, simultaneously measuring and recording the photons coming from all the sources in the field of view. Because each CCD image records th… See more

    Software

    A number of free computer programs are available for synthetic aperture photometry and PSF-fitting photometry.
    SExtractor and Aperture Photometry Tool are popular examples for aperture photometry… See more

    Organizations

    There are a number of organizations, from professional to amateur, that gather and share photometric data and make it available on-line. Some sites gather the data primarily as a resource for other researcher… See more
