Data Set S1 shows the High Altitude Mapping Orbit (HAMO) and Low Altitude Mapping Orbit (LAMO) images used in this study. Data Set S2 contains the crater counts and estimated ejecta thicknesses estimated in this study. We strongly recommend reading the details the contents of this file to properly understand the structure of each Data Set. Data Set S1 content: Requirements: None. The contents of Data Set S1 are Dawn image information. - File 1: HAMO.csv; Description: CSV file containing HAMO image information - File 2: LAMO.csv; Description: CSV file containing LAMO image information - File 3: Additional_LAMO.csv; CSV file containing additional LAMO images for Occator and Haulani. - File 4: ReadMe.txt; Description: TXT file with content description Data Set S2 content: Requirements: A Python script is included in Data Set S2. The script needs all CSV files included in Data Set S2 in the same directory. - File 1: meta.csv; Description: CSV file containing host crater file names - File 2: Occator.csv; Description: pre-ejecta crater data from Occator - File 3: Haulani.csv; Description: pre-ejecta crater data from Haulani - File 4: Cacaguat.csv; Description: pre-ejecta crater data from Cacaguat - File 5: Dantu.csv; Description: pre-ejecta crater data from Dantu - File 6: Ikapati.csv; Description: pre-ejecta crater data from Ikapati - File 7: tmax.csv; Description: crater rim ejecta thickness data - File 8: plotProf.py; Description: Python script that reproduces Figure 8 Data Set S3 content: Requirements: None.
