History of Simu Trig Thresholds for EEMC pi0s
This is for my own reference mainly, to try to keep track of the values I have used. The setup files for the simu trig has the following trigger settings. I have not found other documentation yet to verify the values. The values listed are the HT and TP in GeV.
# Apr 06 20:28:47 to May 10 20:47:14 (pp transverse) 3.40 5.40 # May 10 20:47:14 to May 13 21:52:48 (pp 2nd longitudinal) 2.90 4.50 # May 13 21:52:49 to May 16 00:45:00 (pp 2nd longitudinal) 3.70 5.10 # May 16 00:45:01 to June 07 23:40:11 3.7 5.2The Pythia and BFC filters use values of
3.8 5.0The max values used would then be 3.8 and 5.4 GeV, and 10% above max would be 4.18 and 5.94. It seems the values I have used are
Oct 5th: 3.7 5.2 Oct 11th: 3.9 5.5 Oct 11th, after the spin meeting: 4.2 6.0
The Oct. 5 was based on the highest thresholds in data. The Oct. 11th (not after the meeting) are basically 5% more than the Oct 5th values, i.e. 5% more than highest in data (but not 5% above highets in the MC). The Oct 11th "after meeting" values are intented to be 10% above the highest in data and MC. On Jan 11th, the MC was set to 3% higher than data, or
Jan 11th data: 4.2 6.0 Jan 11th MC: 4.326 6.18
To keep track of these values, I've defined my own trigger set letters. There are 5 values previously identified as a-f when labeling the L0 thresholds (See this blog). So I'll start labeling these various L2 levels from 'f' since the L0 level corresponds.
HT [GeV] | TP [GeV} | |
---|---|---|
f | 3.7 | 5.2 |
g | 3.9 | 5.5 |
h | 4.2 | 6.0 |
i | 4.326 | 6.18 |
