preprocess_spectra

pydl.pydlspec2d.spec1d.preprocess_spectra(flux, ivar, loglam=None, zfit=None, aesthetics='mean', newloglam=None, wavemin=None, wavemax=None, verbose=False)

Handle the processing of input spectra through the combine1fiber() stage.

Parameters:

flux : array-like

The input spectral flux.

ivar : array-like

The inverse variance of the spectral flux.

loglam : array-like, optional

The input wavelength solution.

zfit : array-like, optional

The redshift of each input spectrum.

aesthetics : str, optional

This parameter will be passed to combine1fiber().

newloglam : array-like, optional

The output wavelength solution.

wavemin : float, optional

Minimum wavelength if newloglam is not specified.

wavemax : float, optional

Maximum wavelength if newloglam is not specified.

verbose : bool, optional

If True, print extra information.

Returns:

tuple() of numpy.ndarray

The resampled flux, inverse variance and wavelength solution, respectively.
