Notes. SDSS sample, narrow lines (n = 344). The first column is the CIG catalogue number. The other columns are the different line ratios used in the diagnostic diagrams. The presence of an upper or a lower limit is indicated with a “ < ” or a “ > ” symbol, respectively. The precision of the numbers is adjusted for the error to have two significant digits.
