Description
    Extended Antoine equation for the vapour pressure.
 
    \f[
        \log (p) = A + \frac{B}{C + T} + D \log (T) + E T^F
    \f]
 
    Coefficients \f$A\f$, \f$B\f$, \f$C\f$, \f$D\f$, \f$E\f$ and \f$F\f$ are
    to be supplied and should be suitable for natural logarithms and
    temperatures in Kelvin.
