jaxqsofit.defaults.build_default_prior_config(flux, line_config=None, include_elg_narrow_lines=False, include_high_ionization_lines=False, pl_pivot=None)[source]#

Build a full PriorConfig with sane defaults from data flux scale.

Parameters:

  • flux (ndarray) – Input flux array used to set data-scale-aware defaults.

  • line_config (dict or None, optional) – Optional line configuration override. If None, default line config is used.

  • include_elg_narrow_lines (bool, optional) – If True, append additional narrow ELG lines from DEFAULT_ELG_NARROW_LINE_PRIOR_ROWS to the active line table.

  • include_high_ionization_lines (bool, optional) – If True, append additional high-ionization lines from DEFAULT_HIGH_IONIZATION_LINE_PRIOR_ROWS to the active line table.

  • pl_pivot (float or None, optional) – Optional manual override for the power-law continuum pivot wavelength in Angstrom. If None, the model uses the midpoint of the fitted rest-frame wavelength coverage.

Return type:

Dict[str, Any]

Notes

reddening_a2500 controls the amplitude of the built-in SMC-like attenuation curve. Because the curve is normalized to unity at reddening_uv_ref (2500 Angstrom by default), this parameter is \(A(2500)\) in magnitudes rather than literal E(B-V).

jaxqsofit.defaults.build_default_bal_components(flux)[source]#

Return built-in BAL custom components with flux-scaled depth priors.

Parameters:

flux (ndarray)

Return type:

tuple[CustomComponentSpec, …]
