  • Fix reading of PixelDisabled objects when n_trigger_disabled != n_HV_disabled. PR: #219, issue #218

- Python
Published by maxnoe over 5 years ago

https://github.com/cta-observatory/pyeventio - v1.4.1

v1.4.1

  • Introduce EventIOFile.peek to look at the next eventio object in a file without advancing the iterator. Beware, that this might prevent from reading the previous object if the file is not back-seekable. To be safe, only call peek after reading/parsing the current object.
  • Fix that SimTelFile.iter_mc_events had the wrong TelescopeData. It always used the last available, which was either the one from the previous event or even older since events might not have TelescopeData at all

- Python
Published by maxnoe about 6 years ago

https://github.com/cta-observatory/pyeventio - v1.4.0

v1.4.0

  • Change to the PhotoElectrons[1208] object: store photoelectrons and amplitudes in 1d-arrays together with an array of pixel ids instead of lists of lists. This brings a considerable performance improvement, both for reading this data from simtel files and for dealing with the data.

See https://numpy.org/doc/stable/reference/generated/numpy.ufunc.at.html for how to do operations on these pairs of indices / values arrays, e.g. to compute the mean arrival time in each pixel, you could use:

```python def mean_at(n, array, indices): mean = np.zeros(len(n)) np.add.at(mean, indices, array)

# avoid divide by zero warning
mask = n > 0
mean[mask] /= n[mask]
mean[~mask] = np.nan
return mean

meantime = meanat(pe['photoelectrons'], pe['time'], pe['pixel_id']) ```

  • The photon_counts field of the PhotoElectrons[1208] object was renamed to photons

Thanks @watsonjj for implementing this in https://github.com/cta-observatory/pyeventio/pull/207
