Event rates vs zenith cut

Here we show the effect of a cut in the reconstructed zenith angle on the event and data rates. We also show the effect in the up-going neutrino signal.
The results shonwn here correspond to the 21-line detector.

Color code: dipolefit, linefit, jams, directwalk.

Corsika events

Distribution of reconstructed zenith angle (first guesses and llhs)

First guesses

Log-likelihood

Rate of events surviving a cut in the zenith angle

First guesses:

Range: 0-180

Range: 60-100

Log-likelihoods:

Range: 0-180

Range: 60-100

Here you can see a table with these results.

We can also translate these numbers into a data event rate taking into account that a trigger at 8 hit DOMs, corresponds to ~10 kB/s.

Cosmic neutrinos

Distribution of reconstructed zenith angles for a cosmic neutrino spectrum:

These plots show the fraction of cosmic signal surviving a cut in the reconstructed zenith angle:

First guesses:

Range: 0-180

Range: 90-100

Log-likelihoods:

Range: 0-180

Range: 90-100

Here you can see a table with these results.

Atmospheric neutrinos

Distribution of reconstructed zenith angles for a atmospheric neutrinos:

These plots show the fraction of cosmic signal surviving a cut in the reconstructed zenith angle:

First guesses:

Range: 0-180

Range: 90-100

Log-likelihoods:

Range: 0-180

Range: 90-100

Here you can see a table with these results.
