Seismic signal data and X-ray CT image data of Hayabusa2 returned samples

Description

This repository includes the signal data used to estimate the elastic wave velocity of Hayabusa2 returned samples and CI, C2 (Tarda and Tagish Lake), and CM chondrites. Also, the X-ray CT image data for Ryugu's C0002-No3 and C0002-No4 samples are available. Both data were used by Onodera et al. (2023). 

Signal_data

Time series data are included in "csv format" in the following folders.

• Ivuna
• Murchison
• Ryugu (C0002-No3, C0002-No3-1, C0002-No3-2, C0002-No4-1, C0002-No4-2)
• TagishLake
• Tarda (Tarda-No0, Tarda-No1, Tarda-No3)

In each csv data, the first column shows time in seconds where 0 corresponds to the trigger time (i.e., one can use the data t > 0 s for analysis). The second to sixth columns correspond to the signal data (N=1,2,...,5 measurements). The background noises have already been removed from both "No sample signal" and "Sample signal".

CT_data

X-ray image data were included in "TIFF" format for "C0002-No3" and C0002-No4", respectively.

The number in each file name corresponds to 1 slide of scanning with a voxel resolution of 3.4 μm.
