broad2lick

paintbox.broad2lick(wl, intens, obsres, vel=0)

Convolve spectra to match the Lick/IDS instrumental resolution.

Broad a given spectra to the Lick/IDS system resolution. The resolution of the IDS varies as function of the wavelength, and we use the mean interpolated values from the appendix of Worthey and Ottaviani 1997.

wl (array) :

Wavelenght 1-D array in Angstroms.

intens (array):

Intensity 1-D array of Intensity, in arbitrary units. The lenght has to be the same as wl.

obsres (float or array):

Value of the observed resolution Full Width at Half Maximum (FWHM) in Angstroms.

vel: float

Recession velocity of the measured spectrum.

array_like

The convolved intensity 1-D array.
