Generate a list of templates for fitting to the grism spectra

The different sets of continuum templates are stored in

>>> temp_dir = os.path.join(GRIZLI_PATH, 'templates')
Parameters
fwhmfloat, optional

FWHM of a Gaussian, in km/s, that is convolved with the emission line templates. If too narrow, then can see pixel effects in the fits as a function of redshift. Default is 400.

line_complexesbool, optional

Generate line complex templates with fixed flux ratios rather than individual lines. This is useful for the redshift fits where there would be redshift degeneracies if the line fluxes for individual lines were allowed to vary completely freely. See the list of available lines and line groups in get_line_wavelengths. Currently, line_complexes=True generates the following groups:

Ha+NII+SII+SIII+He OIII+Hb OII+Ne

starsbool, optional

Get stellar templates rather than galaxies + lines. Default is False.

full_line_listNone or list, optional

Full set of lines to try. The default is set in the global variable DEFAULT_LINE_LIST.

The full list of implemented lines is in get_line_wavelengths.

continuum_listNone or list, optional

Override the default continuum templates if None.

fsps_templatesbool, optional

If True, get the FSPS NMF templates. Default is False.

alf_templatebool, optional

If True, include Alf templates. Default is False.

lorentzbool, optional

If True, use Lorentzian line profiles instead of Gaussian. Default is False.

Returns
temp_listdictionary of SpectrumTemplate objects

Output template list
