Thermal expansion coefficient over haline contraction coefficient (48-term equation)
gsw_alpha_on_beta(SA, CT, p)
Absolute Salinity [ g/kg ]
Conservative Temperature [ deg C ]
sea pressure [ dbar ]
ratio of thermal expansion coefficient to haline contraction coefficient [ (g/kg)/K ]

This yields the ratio of the return values from gsw_alpha and gsw_beta, to within computational precision.
