Caption: Figure 8.

Discovery and follow-up photometry obtained for NGTS-EB-8. Top-left panel: phase-folded photometry for the primary eclipse in each instrument, offset for clarity. Binned data in 2 minute bins for NGTS and 15 minute bins for all other instruments is shown as solid circles, with raw data shown as lower opacity points. The median best-fit allesfitter model for the High k-range model is shown as a solid line for each photometric data set. Top-right panel: phase-folded photometry for the secondary eclipse in each instrument it was observed, offset for clarity. Bottom panels: residuals for the primary and secondary eclipses in each instrument, offset for clarity. The photometric data are provided as the data-behind-the-figure.
