split_spline_template¶
- grizli.utils.split_spline_template(templ, wavelength_range=[5000, 24000.0], Rspline=10, log=True)[source]¶
Multiply a single template by spline bases to effectively generate a spline multiplicative correction that can be fit with linear least squares.
- Parameters
- templ
SpectrumTemplate Template to split.
- wavelength_range[float, float]
Limit the splines to this wavelength range
- Rsplinefloat
Effective resolution, R=dlambda/lambda, of the spline correction function.
- logbool
Log-spaced splines
- templ
- Returns
- stempdict
Dictionary of spline-component templates, with additional attributes:
wspline = wavelength of the templates / spline correction tspline = matrix of the spline corrections knots = peak wavelenghts of each spline component
