crackz

mpdaf.sdetect.crackz(nlines, wl, flux, eml, zguess=None)

Method to estimate the best redshift matching a list of emission lines.

Algorithm from Johan Richard (johan.richard@univ-lyon1.fr)

Parameters:

nlines : int

Number of emission lines

wl : array of float

Table of observed line wavelengths

flux : array of float

Table of line fluxes

eml : dict

Full catalog of lines to test redshift

zguess : float

Guess redshift to test (only this)

Returns:

out : (float, float, int, list of float, list of float, list of str)

(redshift, redshift error, list of wavelengths, list of fluxes, list of lines names)
