Analysis¶

class gammapy.analysis.Analysis(config)[source]

Bases: object

Config-driven high level analysis interface.

It is initialized by default with a set of configuration parameters and values declared in an internal high level interface model, though the user can also provide configuration parameters passed as a nested dictionary at the moment of instantiation. In that case these parameters will overwrite the default values of those present in the configuration file.

Parameters
configdict or AnalysisConfig

Configuration options following AnalysisConfig schema

Attributes Summary

 config Analysis configuration (AnalysisConfig)

Methods Summary

 Produce reduced datasets. Calculate excess map with respect to the current model. Calculate flux points for a specific model component. Calculate light curve for a specific model component. Fetch observations from the data store according to criteria defined in the configuration. read_models(path) Read models from YAML file. Fitting reduced datasets to model. set_models(models) Set models on datasets. update_config(config)
