Hi Justin,

 

Thanks for your comments. There is an updated version here

 

Thanks,

Hi Ejiro,

 

Very nice job!  Your presentation of this already at our Calo Calibrations mtg was appreciated too, I think we already got some comments there, so I don't know if there will be a formal approval procedure, but as convener of _a​_ relevant meeting for this, it would probably meet my approval once you've considered the items below.  

 

Comments:

 

The 2nd bullet on Slide 2 ("Hadrons traversing the HCALs shower

due to the plates ...") could (probably _should_) be improved maybe into a couple separate major bullets...my issues with it are 1) it kind of describes how all sampling calorimeters function [it be nicer to say something specific about our hcal] and 2) it's a little too maybe inaccurate, maybe too basic, maybe non-specific, in the language of "deposits energy into the tiles"  e.g. it also deposits energy into the absorbers too..so maybe sharpen these or just make some other points instead --like maybe other details of the parameters of the Hcal, maybe expand some of the points in the first bullet too --     Some alt suggestions: "Unique ["tilted Shashlik"|tilted absorber|...]  sampling design.  (sub bullet Extruded Polystyrene Scillintilating tiles" , "Kuraray Y11 Wavelenghth Shifting Fibers " .... "  "[tilt design leads to] Very high uniformity in phi response."  ... "Hammamatsu SiPM Readout For each Tile Summed 4(Inner Hcal) or 5(Outer Hcal) Tower-unit Signals" ...  somewhere around here you should definitely have something like these :  "Towre Etax Phi Segmetation 0.1x0.1"    and especially one of these:  "Tower units projective in Eta" since that's one of its strengths.  (adding another small plot that shows this might fill some more space too, an example is attached below)

 

Slide 3  2nd bullet  first "have" --> "has"

 

Slide 4  plots  formula look good in combo as discussed at our mtg... For the plots on the bottom 2/3rds of the slides, it would be a little better if the fit plots were on the left (how one C is derived for each calo), and then the tower distributions (C for all towers for each calo) on the right since that is the order they are obtained.

 

--Several places:   Am I missing the the lack of the bibliography associated with the [1], [2], ... citations?
