We find that the observed dependencies (scaling) of long-range beam-beam
effects on the beam separation and intensity are consistent with the simple
assumption that, all other parameters being the same, the quantity preserved
during different set-ups is the first-order smear as a function of amplitude.Comment: 8 pages, contribution to the ICFA Mini-Workshop on Beam-Beam Effects
