2. Data taking & data processing
Line 1
operational since
March 2nd, 2006
Offline track reconstruction
Physics events
when enough correlated hits
are found
online data processing farm
look for a muon-like signal using
all registered hits
DataFilter PC
all data

3. Line 1 Reconstruction uses first hit on a storey scan over directions
3-parameter fit, find all local minima
for each local minimum, fit theta
4-parameter c2 fit
best-fit selection, sort on c2 /dof

4. Hit time residuals
muon bundles
scattered light
line shape

5. Display of a downgoing muon

6. Downgoing muon

7. Atmospheric muon bundles

8. Cherenkov cone

9. Showers

10. Monte Carlo simulation of shower

11. Multiple showers

12. Zenith angle of atmospheric muons

13. Upgoing muon candidate

14. Event times

15. Conclusions Line 1 operational First results
Ambiguity suppressed using hit amplitudes
Observation of individual showers
Line 2 operational in ~4 weeks
