Dear Luke,

Your updated poster looks quite good.  Is it possible to decrease the white space in the plot triptychs in 'Ion Tail Shape' and 'Dependence on Max ADC'? Since you have some vertical space remaining, but not horizontal, internal trimming and resizing would let them be more prominent without encroaching on the boundaries of the section bubbles.

Aside from this, I have no comments.  If no one else weighs in, I think you're good to go.

Hi all,

I uploaded a draft of my QM poster to Invenio along with an updated internal note. The link is at, (https://sphenix-invenio.sdcc.bnl.gov/me/requests/23c856f3-b12d-4e4c-98fc-d5045a29713e).

Following the distortions meeting from yesterday, I also decided to look deeper into Ross' comment about negative ADC values. I found that my histograms were mistakenly excluding negative ADCs and this has since been corrected. As a result, my 2D histogram plots from yesterday now have a baseline centered on zero as they should.

Since I'm no longer excluding negative ADCs, the ion tail regions in my max + neighboring pad profile plots have also become somewhat noisier. I'm not sure what is best to show at QM now so I've proposed two new versions of the ion tail plot in my internal note. Let me know which, if either, can be included on my poster.

I also played around with different scaling factors for the profile plots and decided to scale each curve by the peak ADC value of the largest profile (this is explained in my internal note). Hopefully this is more clear than the integral I was using before.

Lastly, I've added a plot showing the raw waveforms across an entire pad row for a single event (the same event and pad row that my baseline shift plot was taken from). None of the pads beyond 40 or so showed any significant signals above or below pedestal so I excluded them from the plot to focus on the region of active pads.

Please let me know your thoughts on these changes and the poster draft when you get the chance.

Best,

Luke
