CHICOS Analysiscut2
CTShower Code
Running analysiscut2 on old data:
New Showers
Current state of autoFit4:
- Cut on radius at 8 km.
- Cut on time at 25 us.
- After first reconstruction, deletes hits outside 2-sigma time errors.
(There is no requirement that the reconstruction match the intensity well.)
Repeats reconstruction and checks again. (Generally one iteration is all that
is required.)
- Forces 2-sigma errors to be at least 2us for the purpose of selecting hits.
*NEW* Using flat cutoff of 5 us instead of 2-sigma error bars.
- Ignores showers that have fewer than 3 match sites that reconstruct
within 2-sigma error bars. (Currently does not check whether the trigger
site reconstructs well.)
- Requires 2 sites be fit within 2-sigma intensity error bars, with
intensity > 0.1 (so fitting 0 to 0 doesn't count).
- Rejects showers if they are only Chiquita showers after bad sites
have been removed.
To get an idea of how this code performs, I ran it on the current set
of 120 Best Candidate showers.
96 Showers which pass with good data. Below is the previous list
of reconstructed showers, with changes marked.
Complete list of 96 Best Candidate showers:
I also ran this code on the Other Possible showers and
recovered 42 (previously 58). Many that now fail had very
high reconstructed energy (10^20 eV or higher).
Energy distributions:
The Other Possible showers still have proportionally more high-energy showers.
