Note: there is a time shift (abt. 5 minutes) between the two curves because the exact onset of temperature rise is not known and is simply set to the beginning of heating here. Also, a tecnical error (use of Windows software Excel) produces a slightly false cut-off curve of heating power at the end. A better diagram will be shown here in the future|300px|thumb]] | [[image:RF_14012011_tp2.jpg|superimposed temperature-curve and curve showing heating power.
