Scatter plot illustrating the durations of flares τ (upper panel) and the magnitude of abnormal rotation rates ARR (lower panel) versus the area A of the sunspots. In both the panels, the red continuous line represents linear least-squares fit of the form τ = (16.153 ± 0.244) + (0.014 ± 0.001)A (upper panel) and δΩ = (1.579 ± 0.018) + (0.001 ± 0.000)A (lower panel). The diamond symbol in red represents NARR points. Correlation co-efficient and its significance for the least-squares fit are 0.12 and 99.99% (upper panel) and 0.14 and 99.99% (lower panel), respectively.
