The values of D1, D2, log H1, and log H2 are read
Quick methodThis method uses a gamma
directly from the graph. The mathematical
gauge (fig. 2-8). The arrow of the gauge is placed on
computation for this method is shown at the top of
the straight-line section of the curve with its base line
parallel to the log-H axis. Gamma is indicated where
