Integrated asymmetry calculation

[math] Asymm = \frac {\sum (\frac{up(ii)}{Wup}-\frac{upbg(ii)}{Wupbg})-(\frac{sd(ii)}{Wsd}-\frac{sdbg(ii)}{Wsdbg})} {\sum (\frac{up(ii)}{Wup}-\frac{upbg(ii)}{Wupbg})+(\frac{sd(ii)}{Wsd}-\frac{sdbg(ii)}{Wsdbg})} [/math]


Different cases was analysed:
Det A:

  • [math]D_2O[/math] up, files# [40,56,102,108,134,205,210,230];
  • [math]H_2O[/math] up, files# [44];
  • [math]D_2O[/math] side, files# [48,74,78,82,86,90,94,146,180,190,225,235];
  • [math]H_2O[/math] side, files# [52];

Det C:

  • [math]D_2O[/math] up, files# [49,75,79,83,87,91,95,147,181,191,226,236];
  • [math]H_2O[/math] up, files# [53];
  • [math]D_2O[/math] side, files# [41,57,103,107,135,206,211,231];
  • [math]H_2O[/math] side, files# [45];

The results are (File:Asymm table.pdf):

  • Table 1: Det A, weighted with NaI detector
  • Table 2: Det C, weighted with NaI detector
  • Table 3: Det A, weighted with Ref detector
  • Table 4: Det C, weighted with Ref detector
