conversion factor escf calibration so that a 3rd lusu report will be generated step s 3 then for example 11 data points are collected for both the lusu report 1 and the lusu report 3 upon which sscf calibration will try to minimize all those 11 data points 39 differences in value later all of the corresponding data point 39 s ss es ratio data lusu report 3 lusu report 1 are compared and the minimum difference point and maximum difference point are determined step s 4 the sscf calibration factor for the lusu report 3 will be determined according to data points at the locations having the minimum difference value and the maximum difference value between the lusu reports 1 and 3 such sscf calibration factor so called u201c a u201d will satisfied the following equation a lusu report 3 ss es ratio x k u2212 lusu report 3 ss es ratio x k lusu report 1 ss es ratio x j u2212 a lusu report 3 ss es ratio x j 1 it is noticeable that in this case the data points at x 0 i e k 0 and x 12 94 i e j 12 94 and their related corresponding ss es ratio are chosen because they represent the maximum difference point and the minimum difference point respectively in this case the detailed formula equation is expressed as follow step s 5 new sscf will be.
