You should probably delete fullrun_ccd2_acisf15498_pi14-548_cl_pass1_tfrozen_src11_1.ximg
Either tweak this fit manually starting from fullrun_ccd2_acisf15498_pi14-548_cl_pass1_tfrozen_src11.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
