The outlier occupancy for each frequency channel, combining results from AOFlagger and GRANDWin on a specific observation date (2014 September 23). Occupancy is the proportion of flagged samples from the total analyzed data, ranging from 0 (no flags) to 1 (fully flagged). Since GRANDWin is applied after AOFlagger, the plot reflects three components: clean data, AOFlagger flags, and additional outliers detected by GRANDWin. This highlights how GRANDWin captures extra contamination not detected by AOFlagger.
