Hi Dennis, cc Bulk TG.

I uploaded the updated note to invenio (also attached here). 

In the approval session I had requested for all 3 distributions ( raw, recentered, recentered+shifted). We later decided on just 2 distributions since the two corrections appear to give similar flattened psi_2 distributions. I would like to update those 2 distributions to the raw and the recentered distributions only (also highlighted in the note).

Further investigation confirmed that the shifting correction puts some psi_2 values outside the nominal range. Since I'm already away and have a very shaky internet I do not fully understand this behavior and it warrants further checks. Hence, my withdrawal from the recentered+shifted distribution. I did confirm that the application is correct and that the results we got last year by looking into Ron's old root files do show the same behavior of some small entries outside the range  of +/- pi/2. This is something to follow up on at the Bulk TG.

Best regards,

Ejiro

Hi Ejiro,

Congratulations on the approval of the MBD-based EP Preliminary performance plots.

Here are the notes I took about plot changes: 

Y-axis label
Add label on event statistics 
Let’s only show the recentered +  shifted
Please check  artifacts in the very first/last bin - do those bins end at +/- pi/2? 
(And of course changing “Internal” -> “Preliminary” and adding a date of approval in the upper right) 

Can you let me know when you have final versions of these along with a final version of the note?
