Method: 2D Spectroscopy • Superimpose a system of fringes on the coronal image • Get all the spectral information in one image: Fe XIV: 5303 nm (coronal matter, 1.8x10 6 K) Fe X: 637.4 nm (coronal holes, 1.0x10 6 K) He I: 587.6 nm (cold matter, 1.0x10 5 K) • Tilt the F-P to displace the fringe pattern and improve the spatial coverage • Scientific quantities: Ion densities (from intensities) Temperatures (line broadening and comparison with W-L) Velocities (Doppler shifts) Turbulence (non thermal velocities)
Fabry-Perot & 2D Velocity Measurement • This solution has already been validated by several eclipse experiments on ground • Coronal interferogram on FeXIV emission line obtained during a total eclipse (Feb. 16 th 1980) has allowed to derive: intensity, Doppler shift, line broadening and splitting Desai, Chandrasekhar & Angreji, 1982
