Relative increase in principal axis ratios between initial and final snapshot for all merger simulations. Top: intermediate axis over major axis (b/a); bottom: minor axis over major axis (c/a). The axis ratios are computed with the major axis length equal to 1 kpc h^-1 for the panels on the left and equal to 3 kpc h^-1for the panels on the right. Shown are 16 simulations of four disky dwarf galaxies with two sets of initial scale heights and two different satellite orbits: the most massive disk (disk1; black), the intermediate disk (disk2; blue), the least massive disk (disk3; red), and the FNX-analog (green). The color and line coding is the same as in Figs. 3 and 4. Note that the b/a and c/a values are relative to the initial value so they can both become greater than 1.
