The graph of Figure 3 was generated using physica (see the macro file shown in Appendix B). The data points are shown as well as the curve representing the least-squares fit to the data. physica reports the value of the slope of the graph to be $-21452\pm801$, which is equal to $h\nu/k$. Thus from the graph one can determine everything.
