*.par-file, peak list of i-th interval in internal form. If this file exists at starting time, is will be used as input for starting parameters. Normally, this entry is generated by TEIL automatically.
*.par-file will be used for starting parameters, OUTPUT[i] will not be used.
You must enlarge EPSILON for bad grain statistic (e.g. 5µ grains and both primary plus secondary soller slits). Otherwise INDEX will fail: EFLECH finds ghost peak multiplets. Such multiplets are caused by errorneous peak shape due to bad grain statistic.
