Non-thermal electron spectral indices derived from both X-ray energy spectra (black) and radio flux density spectra (blue) over time. The average values is taken during the time of the second X-ray peak after 11:01 UT (after the dashed line). This gives mean values of δ_radio = 3.2 ± 0.3 and that from X-ray being δ_Xray = 2.9 ± 0.5. This is indicative of both radio and X-ray emission being produced from electron populations with similar characteristics for example, the electrons producing thin-target X-ray emission may be closely related to those which produce radio.
