3.2.10.5 SplineDef section
Sections of this type define global splines, witch can be referenced within DAC
voltage definitions later in the configuration file. This section has a single entry with
name “points”, its value is a sequence of the spline grid points. The sequence can
have any length, but must be written as a single line of text.
An example for a [SplineDef] section is:
[SplineDef] MyLensMode_T2
{
Points = (1,0.6),(5,3.0),(7,3.78),(10,4.5),(20,6.0),(100,7.3),(150,6.0)
}
Entry Type Description
Points point
sequence,
mandatory
A list of RR-NL pairs, where RR is the retarding ratio
(Ekin – WF)/Ep and NL is a nonlinear factor used in
the lens voltages definitions.
The spline will be called as MyLensMode_T2(-(-$Ekin-
$WF)/$Ep) and would return an interpolated NL-
value.
