Furthermore, every 2272200100038 individual AMS-measurement contributes to the total 2272200100039 error which can turn out to be the main error for the 2272200100040 case of low isotopic ratios-below 10E-13. In case of 2272200100041 Al-26 determination, the current was exceptionally low,2272200100042 the number of events recorded was small and hence the 2272200100043 statistical error was rather large. Finally, the 2272200100044 chemical separation leads to an error of about 3%. 2272200100045 Combining the individual errors in quadrature was 2272200100046 obtained the total error of each cross section value. 2272200100047 (EN-ERR).The error is reported by authors. 2272200100048 STATUS (TABLE) .From TABLE in RCA,88,829,2000 2272200100049 (SPSDD,31531001) Entry deleted.
