Figure S6. The relativistic electron PSDs for μ = 630,
1096, 2290, and 3311 MeV/G at selected L* before or at the onset
of the intense substorms (PSD40 ,PSD50 , PSD60 , andPSD70 ) versus the MeV electron PSD variations
(PSD41/PSD40 ,PSD51/PSD50 ,PSD61/PSD60 , andPSD71/PSD70 ) for 29 intense
substorm events from January 2013 to April 2015.
