    keyword=A Closer Look at too wide Lumi Asymmetries and beam raster size

    It looks like the raster was fine before the Moller measurement was taken and after it was done when we asked for 6x6 MCC raster we weren't given it. Below the first plot (Run # 25888) is before Moller, the second (Run # 25891) is the spot++ following the Moller and the third (Run # 25892) is the first production after the Moller. The raster was fine before the Moller. After the spot++ I read the raster as being 4x4 mm^2 which is what 6x6 MCC raster should give and continued on with production running. Looking at the first run after production it is obvious that the raster size had shrunk below 4x4 mm^2.
