Measurement parameters

${\mathcal{D}}_{\mathrm{rate}}$ (kGy μs−1)	fFEL(MHz)	τp(ns)	Tcvd(%)	〈Φc〉(108ph/pls)	Ntrain	Np
1.06	1.13	886	0.6	1.59	2800	144
2.04	2.26	443	0.6	1.53	9200	200
2.55	1.13	886	1.4	3.82	2000	144
4.75	2.26	443	1.4	3.56	5200	200

${\mathcal{D}}_{\mathrm{rate}}$ is the average dose rate, f_FEL is the XFEL frequency, and τ_p is the time between successive pulses which defines the the minimum XPCS delay time. T_cvd 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, 〈Φ_c〉. N_train is the number of pulse trains averaged in the analysis. N_p is the maximum number of pulses per train.
