Analysis Results for the systematic shift in φ

Line: 8 to 10
  The matching is performed as follows:
  • Take an L1 Object within |η|<1.25 (HO acceptance)

    • Will be changed to < 0.8 to exploit only the full DT coverage in the barrel
 
  • Loop over all HORecHits
    • Find a hit that lies within a Grid of +/- one HO tile and shows more than 0.2 GeV (to suppress noise)
    • If another Hit within the range shows more energy than a previously found hit, take the larger energy hit
When plotting Δη vs. Δφ between the L1 information and the HORecHit one can observe that the distribution of values tends towards positive Δφ. The Δφ is calculated by subtracting the L1-φ from the HO-φ.

The L1Muon coordinates are binned:

Changed:
<
<
  • φ bins ≈ 0.0425, center at 0
>
>
  • φ bins ≈ 0.0435, center at 0
 
  • η bins = 0.1, center at 0.05 and -0.05

There is a shift in counting iφ in HO, meaning that Sector 1 consists of iφ 71,72,1,2,3,4. But as the analysis is done using the CMS η and φ this should not play a role except the calculation detId to phi is wrong.
