Bases: object

Derive initial jet-model parameters from observed SED features.

Notes

This helper maps phenomenological SED observables to a physically parameterized jetset.jet_model.Jet configuration.

Methods Summary

`constrain_SSC_EC_model`([name, jet_model, ...])	Build or update an SSC+EC jet model from observables.
`constrain_SSC_model`([name, jet_model, ...])	Build or update an SSC jet model from observables.
`get_model_constraint`([name, jet_model, ...])	Apply observational constraints and return an initialized jet model.

Build or update an SSC+EC jet model from observables.

Parameters:

name (str, optional) – Name for a newly created jet model.
jet_model (Jet, optional) – Existing jet model to update. If omitted, a new one is created.
EC_components_list (list of str, optional) – External-Compton components to activate.
params_grid_size (int, optional) – Grid size used in internal one-dimensional parameter scans.
electron_distribution_log_values (bool, optional) – If True, electron-distribution parameters are interpreted in log space.
R_H (float, optional) – Optional dissipation distance override.
silent (bool, optional) – If True, suppress progress messages.
R_H_within_BLR (bool, optional) – If True, enforce R_H inside BLR when relevant.
R_H_within_DT (bool, optional) – If True, enforce R_H inside dusty torus when relevant.
disk_type (str, optional) – Disk model type used for EC setup.

Returns:

Constrained SSC+EC jet model.

Return type:

Jet

Apply observational constraints and return an initialized jet model.

Parameters:

name (str, optional) – Name used when creating a new jet model.
jet_model (Jet, optional) – Existing jet model to constrain. If omitted, a new one is built.
EC_components_list (list of str, optional) – External-Compton components to activate.
params_grid_size (int, optional) – Grid size used by numeric scans for B and R constraints.
electron_distribution_log_values (bool, optional) – If True, distribution parameters are interpreted in log space.
silent (bool, optional) – If True, suppress progress output.
R_H (float, optional) – Optional dissipation distance override.
R_H_within_BLR (bool, optional) – If True, clip R_H inside BLR when disk/BLR is enabled.
R_H_within_DT (bool, optional) – If True, clip R_H inside dusty torus when enabled.
disk_type (str, optional) – Disk model type for EC setup.

Returns:

Constrained jet model ready for evaluation and fitting.

Return type:

Jet

Raises:

RuntimeError – If beaming mode or emitter spectral type is not compatible.
