ewoksid02.tasks.scalerstask.ScalersTask#

class ewoksid02.tasks.scalerstask.ScalersTask(inputs=None, varinfo=None, node_id=None, node_attrs=None, execinfo=None, profile_directory=None)[source]#

Bases: ID02ProcessingTask

The ScalersTask class is responsible for creating a scalers file, that contains a large chunk of the metadata for reprocessing. It extends the ID02ProcessingTask class and provides additional functionality to apply a standard pyFAI normalization: - Methods to read monitor values from the metadata file or from blissdata - Methods to read normalization parameters from the metadata file or from the headers - Methods to cache pyFAI azimuthal integrator and apply normalization

Parameters:

  • inputs (Optional[Mapping])

  • varinfo (Optional[dict])

  • node_id (Union[str, int, tuple, None])

  • node_attrs (Optional[dict])

  • execinfo (Optional[dict])

  • profile_directory (Optional[dict])
