In Eq. (6) on page 196 a minus sign should be introduced, so that Eq. (6) reads


or, alternatively, [FORMULA] should be replaced by [FORMULA]. Here [FORMULA] is the velocity behind the shock (usually positive), and [FORMULA] is the velocity in front of the shock (usually negative). In this case we assumed [FORMULA] with [FORMULA] being the amplitude of the flow speed. This assumption corresponds to a symmetric sawtooth-type shock. In this case Eq. (5) follows directly from Eq. (6). In the general case, the LHS of the above given equation should read [FORMULA]. The modified version of the Rankine-Hugoniot equations (see Sect. 2) is however not affected by this assumption.
