Decay of bremmstrahlung emission becomes more steep than
that of 0 emission. It seems that variation of the intensities becomes asynchronious.

If the L>L1 than escaping time shifted to more earlier time.
????
The shortest path of protons L1 =1.055RTime delay of Ep=5 GeV (Vp=0.987c)relative to gamma-ray is 35s Escaping time must be near 06:48 UT Remember that 06:48 UT is the crucial point in the flare development
R=0.984a.e, γ-ray emission time of flight=490.5s time of max NM T NM = 06:52:30 UT corresponds to Ep=500 MeV, than time delay T NM relative γ-ray emission maximum Tγ=06:46:30 UT is equal to 360 s . In this case proton time of flight is Tflight=(490+360) s. Vp (500 MeV)=0.76c. In this case proton path L= Tflight *Vp=1.32R and time
difference between 5 GeV and 500 MeV protons onset time has to be
195 s.
This value correspond l to NM rise time duration..
