Ivt.Thresh()

Type: INSTANCE FUNCTION

Purpose: Sets up threshold conditions which must be met before Ivt.StopAt() tests are performed.

After any of the threshold tests is met, the StopAt criteria are evaluated for the rest of the scan. There are six threshold tests that you can perform:

1.	IMin	I < I_MinThresh
2.	IMax	I > I_MaxThresh
3.	EMin	E < E_MinThresh
4.	EMax	E > E_MaxThresh
5.	Amin	A < A_MinThresh
6.	Amax	A > A_MinThresh

Threshold tests allow you to tune the StopAt tests more carefully. For example, you can avoid a premature experiment termination caused by an initial transient.

In general you only enable one of the threshold tests. The others are turned off by a NIL argument in the function call.

NOTE: Any threshold test starts all StopAt tests. Also, when StopAt testing is enabled, it is never disabled, even if the Threshold test that enabled it is no longer valid.

Usage: Ivt.Thresh(Imin, Imax, Vmin, Vmax, Amin, Amax)

Imin	REAL	Enable StopAt if I < IMin
Imin	NIL	Disable this test
Imax	REAL	Enable StopAt if I > IMax
Imax	NIL	Disable this test
Vmin	REAL	Enable StopAt if E < EMin
Vmin	NIL	Disable this test
Vmax	REAL	Enable StopAt if E > EMax
Vmax	NIL	Disable this test
Amin	REAL	Enable StopAt if A < AMin
Amin	NIL	Disable this test
Amax	REAL	Enable StopAt if A > AMax
Amax	NIL	Disable this test
