• data format is that of a .prn file (can export from excel)
• windows formated EOL: CR+LF
• usually given a .glo extension.
• Format: Columns 1 and 2 are IRF and #counts in the donor channel, respectively. Rows are channels 0, 1, 2, .... Column 3, which specifies the precision of the data (sd) is optional. When omitted, the analysis assumed Poisson noise, where sd = sqrt(n). The header contains, successively,
  • time/channel (ns/chan)
  • start channel of the convolution
  • stop channel of chi^2 calculation
  • start channel of the chi^2 calculation
