Extended Data Fig. 1: Example spectra from various locations and associated model fits.
From: Solar flare accelerates nearly all electrons in a large coronal volume

The central panel (e) shows a reference microwave image at 9.92 GHz at 15:58 UT. ROI1 and ROI2 are shown in green and cyan, respectively. Plus signs, 1 to 8, indicate pixels, for which the observed spectra and model fits are shown in the remaining eight panels (a–d, f–i), each marked with P1 to P8. The asterisks with error bars show the data and the uncertainties at the 1-sigma level; the curves show the corresponding model spectral fits. The fluxes are given in solar flux units (sfu): 1 sfu = 104 Jy = 10−22 W m−2 Hz−1 = 10−19 erg s−1 cm−2 Hz−1.
