Specifically, the level widths V1, V2, V3, and V4 are widths of level intervals between the level amplitudes a1, a2, A3, a4, and a5, that is, widths of level intervals between the level amplitudes a1, a2 are V1; the width of the level space between the level amplitudes A2 and A3 is V2; the width of the level space between the level amplitudes A3 and A4 is V3; the width of the level spacing between the level amplitudes a4, a5 is V4.
