Variations of the LER beam size in X and Y as fctn of HER during the LER=1.2A Her scan

Variations of the LER beam size in X and Y as fctn of HER during the LER=1.2A Her scan. X LER size as fctn of HER. Y LER size as fctn of HER. Very good correlation between the BLLC2081 variation and the LER beam sizes (1). LER Y beam size as fct of HER. BLSC2081 as fct of HER.
