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

Hello all,

I believe I've succeeded in producing the parameters for the align
transforms the tracking group will use—however it is still likely
that there might be bugs or errors in the production of these and
they
need to be checked. I'll look into creating a custom "event" display
but that may take some time; any other ideas for checks are
encouraged.

Units are radians (rad) (alpha, beta, gamma) and millimeters (mm)
(x,
y, z).

Here alpha, beta, gamma are the ZYX Tait-Bryan angles of the
transformation and x, y, z are the displacements to the sensor
center
along sPHENIX global coordinate axes.

I've been committing the codes and data files involved with this
production here:

If you look at the source code and have questions, feel free to
ask.
