Hi Ejiro, et. al,

In all four flattening plots of the North and South MBD, with and without the shift, there seems to be a dip around 0 (rad?).  If the identical procedure is used later on, it will influence anisotropy measurements, etc.

best,

Hi Ron,

I added a z-vertex cut and addressed your recommendations. The new note is attached.

Thanks,

Ejiro

Hi Ejiro,

I don’t think it’s a good idea to publicly show an event plane distribution *without* a z-vertex cut.  How quickly can you reproduce the result including a z-vertex cut?

Regards,

Ron

Dear all,

I would like to seek approval for 2 plots showing the calibration steps of the MBD event plane angles in run 2023 commissioning data. The plots can be seen in the note attached. These plots will be used to discuss the event plane calibration process in my talk at WWND24.

Regards,

Ejiro
