e/The Swift UVOT Photometric System

Information
has gloss	eng: In astronomical photometry, the Ultraviolet and Optical Telescope (UVOT) on the Swift Gamma-Ray Burst Mission observes astronomical objects in its 17-by-17 arc minute field of view through one of several filters or grisms. The seven filters, which are similar to those on the XMM-Newton-OM instrument, cover the near-ultraviolet and optical range. The brightness of an object observed in the three optical filters, called u, b, and v, can be converted into the more common Morgan-Johnson (see the UBV photometric system) magnitudes. The three ultraviolet filters probe a spectral region that is not observable from the ground.
