Analysis typeΒΆ
Each analysis will generate at least one FOM (figure-of-merit) and possibly also a VFOM (vector figure-of-merit), which are typically used in Statistics analysis.
FOM
A scalar which is used to characterize the performance of an analysis in a train/pulse. For instance:
- (Sum, median, mean) of an ROI;
- (Absolute) sum of (part of) the difference curve in a pump-probe analysis;
- Absorption coefficient.
VFOM
An array of scalars which is used to characterize the performance of an analysis in a train/pulse. For instance:
- Scattering curve from azimuthal integration;
- The difference curve in a pump-probe analysis;
| Type | Description | VFOM | FOM |
|---|---|---|---|
| pump-probe | See Pump-probe analysis. | VFOM (on) minus VFOM (off). | Sum of the (absolute) on-off VFOM. |
| ROI | Region of interest. | NA | Defined in ROI FOM setup. |
| ROI (proj) | 1D projection in x/y direction of ROI. | Projection of ROI in the x/y direction. | Defined in ROI projection setup. |
| azimuthal integ | 1D Azimuthal integration of average (pulse) image(s) in a train. | Azimuthal integration scattering curve. | Sum of the scattering curve, the value of the largest peak in the curve, \(q\) of the largest peak, and the \(q\) of the center of mass. |
