  1. In the table, we are indicating the methodology used: AD and ED stand for angular or energy dispersive XRD; DFT: Density-functional theory. We are also indicating the PTM used in the experiments and the EoS model adopted: BM3: 3rd order Birch-Murnaghan; HP: Holland and Powell; Ber: Bermann equation. For the present experiment, we have indicated KCl+He because we have used previously reported data from12 for the ambient T part that were collected in He, while our data (collected in KCl) for the thermal part.
