Hello,

I can give the update next meeting, certainly.

Hi Joseph,

Thank you for making the geometry parameters based on the latest survey.
I think it is good to review how the new parameter is different with the
default one
before committing the new parameter to the tracking software.

I remembered you reported the local ladder geometry before.
I would like to hear the global survey results.

Do you report it at the next INTT meeting?

Thanks,
Takashi
