Descriptions:
The present published datasets are the final products obtained by Hirabayashi et al. (2024, under review by Nature Communications, preprint available through Research Square). This readme describes available data and programs. There are three data sets stored in different folders. 

1. come_geometry: Dataset of the highest-scoring samples that satisfied all conditions for the observed ejecta cone geometry created by the NASA/DART impact on the target asteroid Dimorphos.

2. MAMOS_data: Dataset of the asteroid conditions derived from the MAMOS data (Thirouin et al., 2016, 2018) and the resulting geometric factors.

3. Z_model: Dataset of the Maxwell Z-model parameters determined from the ejecta evolution after the NASA/DART impact.

Each folder has a readme file in PDF format. Refer to it for information on data format and how to use data.
