Fig. : The best fit (green) onto data (red) of ROD 1000172 (related ref. . Three symmetric q-Gaussian have been used (A, B and C). The sum of the squares of the deviations (sum from n=1 to n=660) is equal to 1.25 x 10 -5 . Fig. : The best fit (green) onto data (red) of ROD 1000172 (related ref. . Four symmetric q-Gaussian have been used. The sum of the squares of the deviations (sum from n=1 to n=660) is equal to 6.8 x 10 -6 .
