The red dotted line indicates the signal PDF, the green dashed line indicates the sum of all background PDFs and the solid blue line indicates the sum of these components. The inset shows a close-up of the region 0 . 95 < x < 1 . 02. The pull denotes the difference in each bin between the data and total PDF, normalized to the statistical uncertainty in data. The corrected signal yield N SIG is displayed with statistical and systematic errors.
