Fit templates to a spectrum and make a diagnostic figure

Parameters

inpstr or HDUList or SpectrumSampler

Input spectrum file path or HDUList object or SpectrumSampler object. Default is jw02767005001-02-clear-prism-nrs2-2767_11027.spec.fits.

zfloat, optional

Redshift value. Default is 9.505.

vel_widthint, optional

Velocity width, km/s. Default is 100.

scale_dispfloat, optional

Dispersion scale factor. Default is 1.3.

nsplineint, optional

Number of spline continuum components. Default is 27.

show_contbool, optional

Whether to show continuum. Default is True.

drawsint, optional

Number of draws from the fit covariance to plot. Default is 100.

figsizetuple, optional

Figure size. Default is (16, 8).

rangeslist of tuples, optional

List of wavelength ranges to plot in zoom panels. Default is [(3650, 4980)].

full_logbool, optional

Whether to use full log. Default is False.

eazy_templatesNone or str, optional

Eazy templates to use for the fit. Default is None.

use_full_dispersionbool, optional

Whether to use full dispersion. Default is True.

get_init_databool, optional

If specified, just return the SpectrumSampler object and the design matrix array A

scale_uncertainty_kwargsNone or dict, optional

Scale uncertainty keyword arguments. Default is None.

plot_unitNone, str, Unit, optional

Plot unit. Default is None.

sys_errfloat, optional

Systematic error added in quadrature with the spectrum uncertainties. Default is 0.02.

return_fit_resultsbool

Just return the fit results without making a plot - templates, coeffs, flam, eflam, _model, mask, full_chi2

use_aper_columnsbool, optional

Whether to use aperture columns in the spectrum table. Default is False.

labelNone or str, optional

Label to add to the figure. Default is None.

kwargsdict, optional

Additional keyword arguments passed to SpectrumSampler and make_templates

Returns

If return_fit_results = True, returns a tuple containing the fit results:

templates, coeffs, flam, eflam, _model, mask, full_chi2.

Otherwise, returns None.
