The first trial of the EHE reconstruction

This is first results of the EHE reconstruction (for me).

We use the waveform-based log-likelihood.

I use the parameterized PDF of EHE muon tables made by myself. (See here.) I also tried a bare muon tables to compare.


The angular resolution

The Comparison of angular resolution of my parameterized EHE tables with bare muon tables

Blue: parameterized EHE tables, Red: bare muon tables

The Comparison of angular resolution of my parameterized EHE tables with the first-guess (line fit)

Red: parameterized EHE tables, Black: first-guess

The Comparison of angular resolution between 9 and 80 strings

Red: 80 strings, Blue: 9 strings

The saturation problem

You see clear saturation. We should apply the saturation effect for the expectation, too.

Red: data, Blue: expectation, green: profile of data

10^6 GeV

10^8 GeV

10^10 GeV

The Energy resolution

Now, the energy reconstruction is working somehow. Although, you see a saturation effect here, too.

Red: Energy resolution from the reconstruction.

Blue: Limits from stocastic cascade fluctuation.
