store 'E_mats' in 'param_key'; use plot method with analytical stiffness
reduce analytical offset in plot function by constant factor; add
analytical stiffness in epsc-M_asc plot method
set E_mat = E_c
'format_plot', calibration tests from 'TT-SH2' for different E;
import 'format_plot'; set E_mat in param_name; set figure_size;
set E_mats to E_c
