Best orthogonal trigonometric approximations of functions from classes $L_{\beta,1}^\psi$

We obtain the exact order estimates of the best orthogonal trigonometric approximations of periodic functions that are analogues of the Bernoulli kernels and functions of the classes $L_{\beta, 1}^\psi$ in the space $L_q$, $1&lt; q&lt;\infty$
