Presentation Transcript

  1. IceTop reconstruction with rime (an update) Dmitry Chirkin, LBNL

  2. Improvements/updates to code a number of bug fixes refactored and optimized reconstruction code particle density fluctuations are now distributed log-normally. This leads to a self-consistent description of fluctuations (previously density fluctuations had to be rescaled to yield reasonable results) a new SAF (Stefan Arne Fabian) parameterization of density term is implemented. A new parameter describes the curvature of the particle density growth with distance and may turn out to be useful to separate photonic from ionic showers.

  3. Shower profiles

  4. DOM distance profile

  5. Lateral profile

  6. Lateral profile (normalized)

  7. IceTop – in-ice coincidence plots

  8. Summary IceTop reconstruction in rime is quite mature. It includes the latest LDF function and other developments It handles geometrical (shower front fit) reconstruction and LDF fit in one symmetric step, treating both as respective contributions to the llh function several bugs were found and fixed; the code was somewhat refactored and optimized.
