1. Quantitative
 There is no test for Peak Location X or Y. The value of both of these flags is
always zero.
 There is no test for Radius so the flag is always zero.
2. Elliptical
3. Gauss Fit – whole beam
4. Gauss Fit – major axis
5. Gauss Fit – minor axis
6. Top Hat – whole beam
7. Top Hat – major axis
8. Top Hat – minor axis
9. Divergence
This is the same order as listed in sections 5.3.16 through 5.3.21 above under
individual results properties.
Each ‘flag’ will contain one of the following values:
-1 Fail
0 No Test
1 Pass
All results values will be loaded into the array all the time. Results not enabled in
LBA-USB will be zero.
Note: There are three sets of Gauss Fit and Top Hat results. Either the whole beam
section, or the major and minor sections will contain valid results depending on
how LBA-USB is configured.
