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
.
