Best model for ψ Per disk obtained with the LITpro software in the Hα line. On top, uniform (left) and Gaussian (right) 2D map of the disk projected onto the skyplane. East is to the left. On bottom, residual visibilities for ψ Per for the uniform disk model (left) and the Gaussian disk model (right) in the Hα line. Y axes are given in standard deviation σ.
