FRAM data archive

FRAM (F/(Ph)otometric Robotic Atmospheric Monitor) is a series of small robotic telescopes primarily designed for a continuous atmospheric monitoring of astronomical sites in order to measure atmospheric transparency is required with high spatial or temporal resolution. The original FRAM has been operated at the Pierre Auger Observatory in Argentina for more than a decade, while three more FRAMs are foreseen to be used by the Cherenkov Telescope Array (CTA). Two of FRAM sites are equipped, in addition to a primary wide-field teleophoto lens, with a larger diameter traditional telescopes intended for a follow-up and monitoring observations of a wide range of transient objects (gamma-ray bursts, variable stars, comets, etc).
