Notes. “Model” is the model’s name used in this paper, Teff the effective temperature, log g the gravitational acceleration,  [Fe/H]  the metallicity, lx = ly the linear horizontal size of the square-shaped computational box, lz its vertical extent, Nx = Ny the number of grid points in the horizontal directions, Nz the number in vertical direction, T the duration of the simulated time series, Nobm the number of equivalent frequency points considered in the solution of the radiative transfer equation, δIrms/I the relative spatial white light intensity contrast at stellar disk center, vrms the temporal and spatial average of the vertical velocity at Rosseland optical depth unity, “Modelcode” is an internal identifier of the model sequence.
