Frequency extent of bursts from FRB 20240114A as a function of time for Epochs 2–4. Each vertical line represents an individual burst, colour-coded by morphology: simple (blue), complex multi-component (yellow), and drifting (green). The shaded regions indicate flagged frequency ranges due to RFI (light purple) and the instrumental band gap (grey). Side panels show stacked histograms of burst morphologies as a function of time (top) and frequency (right). (An artificial temporal gap is visible in Epoch 2 near 2000 s due to a technical fault during the observation.)
