BRIL DPG session

Conveners: Francesco Romeo (Vanderbilt University), Jose Feliciano Benitez (Universidad de Sonora (MX))

- S3: 
+  left plot suggest to stop x-axis before the statistical noise 
+ in caption "colliding bunches" vs "RHU colliding bins" -> clarify

+ clarify how the "exponential fit" works 
 

- S5: 
+ in caption (a), (b), ... should be placed at beginning of the sentence. Use (left) , (right) instead. 

- S7: 
+ use second/right  y-axis for derivative curve 
 

-S8: 
+ change title of slide, eg. "... Baseline Noise" 
+ in caption it should be clarified there is no signal in these plots, eg. remove the word signal in caption 
 

- S9: 
+ agreed to remove the fit and point out the nMIP points on the plot 

+ error bars on the distribution look too large (compared to the stat variations), suggest to remove them 

 

- S10: 
+ in caption note that some residual collision products are observed when collisions start 
+ why it the background becomes noisy at flat top? 

- S11: 
+ slide is too crowded, should split in two or more
+ in caption state about spread in channels (~50%) 
+ can remove "NC SG" on the plots 


- S12: 
+ split into 2 slides to have more space for caption explanation 

- S13: 
+ change colors that are not visible 

- S14: 
+ clarify what background correction is applied 
+ clarify its all bcids , including train bcid's 

- S16: 
+agree to remove slide
