Investigation of turbulence in the solar photosphere with allowance for influence of the instrumental contour

The solar photosphere turbulence was investigated, taking into account the effect of the instrumental profile. Ten Unno's pairs for the center of the solar disk were observed. The main results are as follows: (1) without taking into account the factors distorting a line, the turbulent velocity in solar photosphere would decrease with height. The values of xi sub t are similar to those of Unno; (2) taking into account the instrument profile, the value of turbulent velocity becomes less, but its dependence on height is the same. The maximum relative error of xi sub t is approximately equal to 13.6%.
