pyhessio

CTA Python wrapper for hessio event format that is used in output of simtel_array.

This is a temporaly solution for testing ctapipe with real CTA MC data.

  • Test Status

Quick Start

Users of the Anaconda python distribution should follow the instructions for Anaconda python distribution.

Dependencies

python3 
setuptools
numpy

build and install

Installation for an anaconda env

conda create -n cta python=3.5
source activate cta
git clone https://github.com/cta-observatory/pyhessio
cd pyhessio  
python setup.py install   

Datasets

To keep the pyhessio code repo small, we have decided to put the example files used for unit tests in a separate repo: https://github.com/cta-observatory/pyhessio-extra :

git submodule init
git submodule update

For pyhessio developers

python setup.py develop

Using pyhessio

### Simple python wrapper for hessioxxx c library. #### Warnings: only ONE simtelarray file could be open at once. 1. This wrapper uses ugly global static variables for development simplicity reason, and because it is a temporally solution until CTA MC data format exists.

2. PROD3 MC use udge amount of memory, and memory is only free when close_file is executed. To force close_file execution, we force to use context manager to instantiate object:

`python with pyhessio.open('pyhessio-extra/datasets/gamma_test.simtel.gz') as f: f.fill_next_event()`
