PLANCK :Planck is a mission of the European Space Agency - ESA. The main objective of Planck was to measure the spatial anisotropies of the temperature of the CMB, with an accuracy set by fundamental astrophysical limits. PLANCK/LFI :The Planck-LFI instrument is an array of 11 radiometric receivers in the Ka, Q, and V bands, with centre frequencies close to 30, 44, and 70 GHz.id:PLANCK/LFI.a |
