where .

In approximation A-1, is a function as in expression 10 and , , and are coefficients determined from the Taylor expansion around .

Notice that we multiply the left-hand side with , so one needs to multiply with .

The coefficients for Equation A-1 are derived in Table 1 and Table 2. , , and have similar expressions as above in Table 2 with , and substited by the corresponding reference values: RMS velocity , average anisotropic parameter and average tilt angles and .
