Notes. Both a PL function and an LP function were used. For each night the observed spectral fits (first row) and EBL-corrected spectral fits using the EBL model from Domínguez et al. (2011) (second row) are provided. The parameters resulting from the fit with an LP (Eq. (4)) are provided when the LP function is preferred with respect to the PL function (Eq. (3)) with a significance higher than 3σ. The fit parameters for 2014 July 19 are reported in Table 3.
