Magnitude of ≥3σ NUV continuum enhancements as a function of GOES flare flux, detected using the IF detection pipeline. The black points with error bars represent the enhancement magnitudes estimated from individual enhanced pixel time series for a specific flare class. A single time series may contain multiple enhanced timestamps and can therefore contribute multiple enhancement magnitude estimates to the plot. A jittered version of this plot, included in the appendix Fig. A.2, shows the density of detections. The total number of flares contributing to these measurements is shown by the red crosses. Stronger enhancements are predominantly observed for the most energetic (X-class) flares.
