Hi all, please find the 3 plots in 1 column at: http://www.slac.stanford.edu/~petrella/tmp/q2plots.eps A issue that I wasn't able to solve is the Y dimension of the bottom plot, which is a little bit less than the other two. This causes also the number of ticks between two successive marked ticks to be 3 instead of 4. Does anyone know why? ciao Antonio
