sPHENIX discussion of software

[Stefan Bathe <stefan.bathe AT baruch.cuny.edu>]

Hi John, Craig, and All,

Just to follow up on the T dependence discussion regarding the difference 
between a T coefficient in the 3 % range and the ~1.5 % you mentioned towards 
the end of the meeting:  this must depend on the reference temperature.

If I take the fit parameters from your slides, John (March 12, 2021, EMCal 
meeting):

S(T) = -25.57*T + 1483

and calculate S(26) and S(20) from that, and then insert that into Hanpu’s 
formula from today’s meeting:  S(T) = S(26)*(1 - alpha(T - 26)) for T = 20, I 
get:

alpha = 0.03125.

Regards,
Stefan
