sPHENIX HCal discussion

[John Haggerty <haggerty AT bnl.gov>]

So my summary of yesterday is:

- We had a fairly clear discussion of calibration with the LED system, 
cosmics, and tracks.  I think I or someone else could write a couple of 
paragraphs explaining a strategy, but let's put that off until after today.

We had some action items:

- Edward was going to define in more detail the logic of a cosmic 
trigger that could give peaks in all towers so we could then figure out 
how to test/simulate it.

- Achim will look into getting a more realistic field map in the outer hcal.

- John and Liang will look at defining a base class for HCAL tower data 
and classes that can versioned for tower data that can encapsulate 
various models of detector response.  [As I write this, I am unsure 
whether this is actually done up to some level, but I don't have time to 
look through the code right now.]

- Eric and Steve will come up with a proposal for LED distribution, with 
the design goal that we can separately fire each of the five tiles in a 
tower.

Of course, correct any of my errors or misconceptions.
