Micha,

an extrapolation of the high temperature data of Sheppard to
temperatures below 100C leads for oxygen isotopes of course to very
high fractionation factors. A combination of the extrapolated Katz &
Matthews  data from 1977 with the new Kim & ONeil 1997 data gives
reliable results. But remember also Land 1980.

Good luck
Michael
