    Description

      When I perform a side-band fit, the result is inconsistent with the equivalent full fit. For example:

      • Side band: 110-115 GeV + 115-160 GeV
      • Full fit: 110-160 GeV
        Here I expect the fits to be equivalent since they cover the same data, but the result is different.

      Attached is a script + workspace to replicate this result, and a png of the plot comparing these fits.
