<li><span>Remove the first and second points from the right hand plots: since these were used to determine the line, we should not get the deviation for these points</span></li><li><span>For the UVa XY modules, please discard the point at 1 uA; the GEM current at this setting is too small to be reliable, and this could be in the charge up region. Please use points 2 and 3 for the line for these modules</span></li></ol>
