VVDS Spectra¶

This class is dedicated to handling the spectra from VVDS galaxy redshift survey, see LeFevre et al. 2013.

The class GalaxySpectrumVVDS is dedicated to handling VVDS spectra

class GalaxySpectrumVVDS.GalaxySpectrumVVDS(catalog_entry, lineFits=False)[source]

Loads the environement proper to the vvds survey.

Two modes of operation : flux calibration or line fitting

Parameters:	catalog_entry – an entry of the vvds catalog calibration – if the class is loaded with intention of flux calibrating the vvds data. lineFits – if the class is loaded with intention of fitting line fluxes on the vvds spectra.

openObservedSpectrum()[source]¶: reads a VVDS pectrum returns the wavelength, the flux and the error on the flux and two arrays for masking purpose

plotFit(outputFigureNameRoot, ymin=1e-19, ymax=1e-17)[source]¶: Plots the spectrum and the line fits in a few figures
