v104 v105 150 150 [[latex($\lambda ' = (u_La_L)*\frac{u_*a_{*L}\lambda}{u_*a_{*L}u_L+a_L}$)]] 151 151 152 for a left sonic rarefaction. For a right sonic rarefaction, the coefficients are slightly adjusted. Note that the entropy fix requires estimates for the velocity and sound speed of the star region, [[latex($u_*$)]] and [[latex($a_{*L} )]]. We get estimates of these using the Roe approach for linearizing the Euler equations. They are listed in Toro, section 11.4.3.152 for a left sonic rarefaction.
