def _reinterpolate(tr, wave, new_wave):
    '''
    Reinterpolate a transmission curve on a fixed, regular wavelength grid

    Parameters
    ----------
    tr : array_like
        Transmission, normalized to 1

    wave : array_like
        Wavelengths vector, in nanometers

    new_wave : array_like
        New wavelengths vector, in nanometers

    Returns
    -------
    tr_regular : array_like
        The reinterpolated transmission

    interp_fun = interp1d(wave, tr, bounds_error=False, fill_value=np.nan)

    return interp_fun(new_wave)
