In order to have an idea of the individual impact by the flare upscaling and the redoing by the McIntosh classifications, the correlation between four lists with flare rates (1988–1996) was calculated providing the slope and correlation coefficient r (between parentheses) obtained by a linear regression forced through the origin. The four series are the McIntosh classifications in this paper with GOES old and GOES new flare counts (resp. JJ old 3d and JJ new 3d) and the NOAA McIntosh classifications with GOES old and GOES new flare counts (resp. NOAA old 3d and NOAA new 3d). The suffix “3d” is to emphasize it concerns classifications done on average every 3 days. All regressions have a p-value < 0.0001. A further discussion is in the text.
