Here in this directory, you can find some plots from the sslt program (run 8774). (E for electron and P for proton) TBT results from recsis using the x(t) function #3: tbt_chi2_xt3.ps tbt_res_doca_xt3.E.ps tbt_res_doca_xt3.P.ps SSLT results from sslt using sslt default x(t) function: sslt_res_doca.E.ps sslt_res_doca.P.ps sslt_ex_res_doca.E.ps sslt_ex_res_doca.P.ps From the minimum of the residual width (one sigma) distribution as a function of doca, we can estimate the single cell resolution at the center of a cell. For Region one, it is about 250 microns and For Region two and three, they are about 350 microns.
