The zip is made of 3 AiiDA exports that contains, for each QSHI candidate:
-The DFT band structures without spin-orbit coupling (group name "band_structures_QSHI_withoutSOC_MCarchive")
-The DFT band structures with spin-orbit coupling (group name "band_structures_QSHI_withSOC_MCarchive")
-The DFPT phonons dispersion without spin-orbit coupling* (group name "phonon_dispersions_QSHI_MCarchive")

*except for jacutingaite, where phonons are not computed using AiiDA.
In fact, jacutingaite phonons are computed using DFPT with spin-orbit coupling, which is 
computationally very intensive and which is run through the GRID parallelization scheme.
In this case the phonon dispersion is contained in the file "Pt4Hg2Se6_phonons.dat"
that is also present inside the zip file.
