To do this the software <br />requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < 4 < 3.0) and a rate <br />of change of Ic. Transitions typically occur when the rate of change of Ic is fast (i.e. delta Ic is small). <br />The SBTn plot below, displays in red the deteded transition layers based on the parameters listed below the graphs. <br />SBTn Index Norm.
