Anotace	High-resolution Thomson scattering system on the COMPASS tokamak (R=0.56 m, a=0.2 m, divertor plasma configuration with ITER-like plasma cross-section) provides electron temperature and density profiles. The spatial resolution in the edge plasma region (~a/100) is optimized for edge transport barrier studies. Formation of characteristic edge profiles (pedestals) is observed during high-confinement mode, i.e. the core electron temperature and density are raised up by the value of pedestal height. Both the Te and ne pedestals are well-fitted by a modified hyperbolic tangent (mtanh) function. In this contribution, a fitting technique of the full radial profiles of electron temperature, density and pressure during H-mode is also described. Electron temperature and density on top of pedestal are statistically processed to find a possible threshold for various types of H-modes.
