All results values will be loaded into the array all the time.  Results not enabled in the LBA-PC 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 the LBA-PC is 

configured. 

 

9.3.1.23 Pass/Fail 

Results 

The PassFailFlag and PassFail properties provide all of the LBA-PC pass/fail test results.   
The PassFailFlag is a combination of all the individual pass/fail results.  The value of PassFailFlag 

is defined as follows: 

Fail 

 

Some test failed 

No test  

No individual test enabled 

Pass 

 

All tests passed 

 
The PassFail property provides individual pass/fail results in a one-dimensional array of integers 

packaged as a Variant.  The pass/fail results are loaded into the array in the following order: 

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 3.1.15 through 3.1.19 above under individual results 
properties. 
Each ‘flag’ will contain one of the following values: 

 

-1   Fail
