Configuration¶

Top-level configuration container for unite models.

Configuration bundles a LineConfiguration, an optional ContinuumConfiguration, and an optional InstrumentConfig into a single serializable object.

All sub-configs can still be serialized individually via their own to_dict / from_dict methods. Configuration adds convenience for round-tripping the combined object to YAML.

Examples¶

Build and save:

>>> from unite.line import LineConfiguration, Redshift, FWHM
>>> from unite.continuum import ContinuumConfiguration
>>> from unite.instrument import InstrumentConfig, RScale
>>> from unite.instrument.nirspec import G235H, G395H
>>> from unite.prior import TruncatedNormal
>>> import astropy.units as u
>>> z, w = Redshift('nlr'), FWHM('nlr')
>>> lines = LineConfiguration()
>>> lines.add_line('Ha', 6564.61 * u.AA, redshift=z, fwhm=w)
>>> cont = ContinuumConfiguration.from_lines(lines.wavelengths)
>>> r = RScale(prior=TruncatedNormal(1.0, 0.05, 0.8, 1.2))
>>> dispersers = InstrumentConfig([G235H(r_scale=r), G395H(r_scale=r)])
>>> cfg = Configuration(lines, cont, dispersers=dispersers)
>>> cfg.save('config.yaml')

Load and inspect:

>>> cfg2 = Configuration.load('config.yaml')
>>> cfg2.lines
LineConfiguration: ...
>>> cfg2.dispersers
InstrumentConfig: 2 disperser(s) ...

class unite.config.Configuration(lines, continuum=None, dispersers=None)[source]¶

Bases: object

Container for a complete unite model configuration.

Parameters:

linesLineConfiguration: Emission line configuration.
continuumContinuumConfiguration, optional: Continuum configuration. None if not used.
dispersersInstrumentConfig, optional: Instrument configuration describing disperser models and calibration tokens. When provided, validate() is called immediately and UserWarning is issued if any calibration axis lacks a fixed anchor.
