Fig. 19


Fitted scale-height of the thick disc of NGC 5981 for the two central axial bins – those with the largest dynamical range – compared to the fitted scale-height while using a dynamical range of only Δμ = 4.5 mag arcsec-2. The fits are done for dynamical ranges Δμ = 4.5−7.0 mag arcsec-2 in steps of 0.5 mag arcsec-2.
