To do this the software <br />requires a range of Ic values over which the transition will be defined (typically somewhere between 1.80 < Ic < 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 detected transition layers based on the parameters listed below the graphs. <br />SBTn Index <br />Ic (Robertson 1990) <br />Transition layer algorithm properties <br />Ic minimum check value:1.70 <br />Ic maximum check value:3.00 <br />Ic change ratio value:0.0250 <br />Minimum number of points in layer: 4 <br />8-2 <br />10 4 <br />12- ,6 <br />14-· ,8 <br />10 <br />1218- <br />14 <br />20- <br />16 <br />22- <br />18 <br />24-r 20 <br />26-22 <br />28-24 <br />30-26 <br />32-28 <br />34-30 <br />36-32 <br />2 34238-b 36 <br />£ 40-£ 38£·42 3) 40 <br />44 1 42 <br />46 44 <br />48 4E <br />50 48 <br />52 4 50 <br />52 <br />54 <br />jot 5E <br />5E <br />6C <br />62 <br />64 <br />66- -,6E <br />68- j y.6E <br />70-·-7C <br />7 <br />74 <br />1 2 3 4 <br />Norm.
