You should probably delete fullrun_pn_xmm0600040101_pi300-10000_cl_pass0_src83_1.ximg
Either tweak this fit manually starting from fullrun_pn_xmm0600040101_pi300-10000_cl_pass0_src83.ximg or adjust the simplespatial fit parameters in $XASSIST/data/missions/*/*/spatial.dat and re-run simplespatial fitting after setting file recreation parameter to yes
