  1. \({{{{{{{{\mathcal{D}}}}}}}}}_{{{{{{{{\rm{rate}}}}}}}}}\) is the average dose rate, fFEL is the XFEL frequency, and τp is the time between successive pulses which defines the the minimum XPCS delay time. Tcvd is the transmission of the diamond attenuators which results in the average number of incident photons per X-ray pulse (ph/pls) on the sample, 〈Φc〉. Ntrain is the number of pulse trains averaged in the analysis. Np is the maximum number of pulses per train.
