[en] Several accuracy tests of the frequencies computation have been performed. They show that for a given model, the frequencies have errors lower than 2 micro-Hz. Several tests have also been made on the Henyey code. They show that the use of the same opacity formula as Bahcall et al. (1983) allows to reproduce their model with a good accuracy. The model has however frequencies systematically 12 micro-Hz larger than found by Ulrich and Rhodes. A model with diffusion of H and He has also been studied. Its frequencies are nearly the same as those of the standard model.
