Shock Ramp Compressions Measurements of Iron on the Sandia National Laboratories' Z-Machine

This data contains 1) the apparent velocity data from Velocity Interferometer System for Any Reflector (VISAR) data analyzed using the PointVISAR program for experiments Z3155 and Z3339 and 2) the equation of state results from analyzing the velocity data using a backward integration -- forward Lagrangian analysis.
These experiments were performed on the Sandia National Laboratories' Z-Machine, where the iron samples were dynamically compressed via shocked compression to approximately 275 Gpa and further ramp compression to approximately 400 GPa. This covers pressure-temperature regions near the melt line as well as the interior conditions of terrestrial planets.
The Z3155 data include four samples, each with two VISAR traces, and the Z3339 data include six samples, each with two or three VISAR traces.
The apparent velocity can be corrected to true velocity using the latest lithium fluoride window correction for a 532 nm wavelength.
PointVISAR is available as part of the Sandia Matlab AnalysiS Hierarchy (SMASH) toolbox.
Details of the backward integration -- forward Lagrangian anaylsis that was used can be found in the related publication.

Example data file interpretation: "Z3155_north_panel_bot_sample_01.txt" is the first VISAR trace from the bottom sample of the north panel on experiment Z3155.
"Z3155_EoS_combined.txt" is the sample-averaged Equation of State result from experiment Z3155.
