ctools

ctools is a software package developed for the scientific analysis of Cherenkov Telescope Array (CTA) data, as well as data from existing Imaging Air Cherenkov Telescopes (such as H.E.S.S., MAGIC or VERITAS).

ctools comprises a set of ftools-like binary executables and Python scripts with a command-line interface allowing for interactive step-wise data analysis. ctools includes also Python modules to control all tools and scripts from within Python. Creation of shell or Python scripts and pipelines is supported as well.

ctools are based on GammaLib, a versatile toolbox for the scientific analysis of astronomical gamma-ray data. Besides CTA, GammaLib supports also the analysis of Fermi/LAT and COMPTEL data, and extensions to support further gamma-ray instruments are planned. An interface to virtual observatory ressources does also exist. By making use of the GammaLib multi-instrument capabilities, ctools supports the joint analysis of CTA, H.E.S.S., MAGIC, VERITAS, Fermi/LAT and COMPTEL data.

ctools are developed by a team of enthousiastic gamma-ray astronomers with support from engineers. We regularily organise coding sprints where key developers but also newcomers meet to discuss the developments and next steps, and advance with the coding of the software.
