The HDF5 file contains the double-hit diffraction patterns from the SwissFEL experiment analyzed in the manuscript.

For each pattern with a specific pulse ID [pid], the following entries are present:
    "[pid]/data": Diffraction data, already background-corrected, as it was given to the reconstruction code.
    "[pid]/mask": Mask of the diffraction pattern. Ones indicate pixels to exclude.
    "[pid]/pid" : Pulse ID
    "[pid]/acq" : Acquisition ID
    "[pid]/run" : Run ID

Patterns are adjusted to have the center at coordinates (512,512).

A minimal python code to visualize the data is provided below:

##########
import h5py
import matplotlib.pyplot as plt
from matplotlib.colors import LogNorm

file = h5py.File("SwissFEL_doublehits.h5")

for entry in file.keys():
    pattern = file[entry]["data"][()]
    mask = file[entry]["mask"][()]
    plt.imshow(pattern*(1-mask), cmap="inferno", norm=LogNorm(vmin=0.2, clip=True))
    plt.show()
