dodal.devices.insertion_device.lookup_table_models.LookupTable

class dodal.devices.insertion_device.lookup_table_models.LookupTable

Specialised lookup table for insertion devices to relate the energy and polarisation values to Apple2 motor positions.

Parameters:

root (dict[Pol, EnergyCoverage] | None, default: None)

Methods

generate(pols, energy_coverage)	Generate a LookupTable containing multiple EnergyCoverage for provided polarisations.
get_poly(energy, pol)	Return the numpy.poly1d polynomial applicable for the given energy and polarisation.

Attributes

model_config	Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
root

classmethod generate(pols: list[Pol], energy_coverage: list[EnergyCoverage]) → Self
