IFSFIT

result = ifsf_fitpoly(lambda, flux, weight, template_flux, index, ct_coeff [, fitord=integer] [, quiet=byte] [, refit=structure])

Function to fit polynomial continuum to spectrum.

Return value

The best fit continuum spectrum (over all wavelengths, not just those fit).

Parameters

lambda in required type=dblarr(N)
flux in required type=dblarr(N)
weight in required type=dblarr(N)
template_flux in required type=any

Ignored. When stellar templates are fit, contatins templates.

index in required type=intarr

Contains indices of continuum regions to fit

ct_coeff out required type=integer default=0

When stellar templates are fit, contains best-fit coefficients.

Keywords

fitord in optional type=integer

Specifies order of polynomial renormalization (default = 3).

quiet in optional type=byte
refit in optional type=structure

If set, contains structure with array of continuum regions to re-fit [tag RAN, type=dblarr(2, X), where X is the number of regions to refit] and array of polynomial orders to fit [tag ORD, type=intarr(X)].
