asgardpy pipeline

Gammapy-based pipeline to support high-level analysis for multi-instruments joint datasets. Follow the Gammapy v1.3 documentation for understanding the core Gammapy objects.

The various Data Levels used here follow the descriptions suggested by GADF v0.3 and CTAO Data Model.

The pipeline was developed with first testing with Fermi-LAT (enrico and fermipy) files and LST-1 (cta-lstchain) DL3 files (with energy-dependent and global selection cuts) for point-like sources.

It also allows for a preliminary analysis of HAWC datasets (stored in Gammapy-readable data). The pipeline can be further expanded to support more types of DL3 files of gamma-ray instruments. See some example notebooks and tests, which use the public data used in Gammapy Tutorials, with an additional Fermi-LAT data.

See Reasons for using Asgardpy over Gammapy v1.3 for a brief overview of the pipeline and its future and Multi-instrument analysis of Crab Nebula for an extended example of the usage of the pipeline.
