Notes. Weighted mean values of the physical parameters of thin and thick discs of each galaxy for the observed data (left values of each column) and for the PSF-deconvolved models (right values of each column). These results are obtained from the vertical fits of the light distribution determined by solving a system of equations that describe two gravitationally coupled vertically isothermal discs (thin and thick discs). The mass-to-light ratios between the thin and thick discs ((M/L)T/(M/L)t = ΥT/Υt) is only obtained for the PSF-deconvolved models. For more details about the parameters, see Sect. 5.2.2.
