Sung,

Thanks for updating the "Standard practices, common practices, and common 
analysis issues for g9a" web page :)

Comments:
* For the z-vertex using GPID (TBTR) you should state what particle is 
being used.

* The CH2 pull angles look OK, but the Butanol lambda angles are 
especially bad. This might be explained by the target magnetic 
holding-field (I think that Eugene and Franz made this sort of statement 
during one of the meetings where you showed these pulls). I added a line 
about this to the wiki (including a link to your webpage).

Let's hope that the holding field corrections get this lambda angle 
problem fixed.

Good job.

Take care,
Michael
