The facility offered by the Salyut 7 vehicle has allowed teams of scientists of 3 CNRS french laboratories to develop an instrument optimized for several disciplines in astrophysics and geophysics. P.I.R.A.M.I.G. (Photography Infra-Red Atmosphere, Interplanetary Medium, Galaxies) is a wide field (10° and 40°) camera devoted to high sensitivity photographic photometry. The spectral range is limited to the visible and near-infrared (400–850 nm), the main advantage being to observe above the absorving and emitting layers of the atmosphere.  相似文献
