Fig. 7.
The first (top) panel shows electron temperatures in the regions A–E with a unit of keV. Second panel shows ionization parameters in the regions A–E with a unit of 1012 s cm−3. Third panel shows the densities of electrons. d2 is the distance to CTB 1 divided by 2 kpc and f0.1 is the filling factor divided by 0.1. The fourth panel shows elapsed times for each region.
