Function Td = mollier_Td_baehr(pv);
returns the dew-point temperature in degrees C for
the given partial vapour pressure of air in Pa.
The inverse of the approximation of Baehr, cited in
Glück 1991, is used. The approximation of Baehr is
cited in the form:
ln(pv) = A - (B / (C + T)),
where A, B and C are constants,
The inverse is therefore:
T = (B / (A - ln(pv))) - C.
The valid range of T for this approximation
is obtained by calling m-file mollier_ps_lim_baehr.m.
