barak.fitcont.spline_continuum¶

barak.fitcont.spline_continuum(wa, fl, er, edges, minfrac=0.01, nsig=3.0, resid_std=1.3, debug=False)[source]¶

Given a section of spectrum, fit a continuum to it very loosely based on the method in Aguirre et al. 2002.

Parameters :

Parameters :	wa : Wavelengths. fl : Fluxes. er : One sigma errors. edges : Wavelengths giving the chunk edges. minfrac = 0.01 : At least this fraction of pixels in a single chunk contributes to the fit. nsig = 3.0 : No. of sigma for rejection for clipping. resid_std = 1.3 : Maximum residual st. dev. in a given chunk. debug = False : If True, make helpful plots.
Returns :	Continuum array and spline points :

wa : Wavelengths.

fl : Fluxes.

er : One sigma errors.

edges : Wavelengths giving the chunk edges.

minfrac = 0.01 : At least this fraction of pixels in a single chunk

contributes to the fit.

nsig = 3.0 : No. of sigma for rejection for clipping.

resid_std = 1.3 : Maximum residual st. dev. in a given chunk.

debug = False : If True, make helpful plots.

Returns :

Continuum array and spline points :
