Display MoreThe 3 curves on the left chart of Fig.4 in the ICCF21 paper (1) seem to refer to the same calibration tests reported on Fig.27 of the 2017 paper (2), but they show important differences between corresponding curves.
Any explanation?
They look to me to be substantially the same, except that the one if paper (2) has been cleaned up a bit so that you can see the lines better.
