Calibration of d180 to temperature was made with a second order polynom, and constrained to fit the borehole temperature profile. T=-211.4(°C)-11.88(°C/‰)*delta-0.1925(°C/‰^2)*delta^2. It corresponds to a temeprature sensitivity of 1.67°C/‰ for the holocene, and 4.33‰/°C for the LGMT. Elevation change needs to be taken into account in addition.
