Description
Data in this archive was used for the study by Lolachi et al. entitled "Ejecta Mass Estimates from the DART Impact Plume Inferred from LICIACube Images". The LICIACube data used in the study were an early-access version released to the team on or about 2023, March 30. Despite being labeled as Level 2, the data is better described as Level 1+. This version of the dataset had been color-separated with bad pixels identified, converted from DN to floating point and corrected for non-linearities.
Data is split into two main categories (and folders within the archive), as described below. Images are named with the format "liciacube_luke_l2_{Identifier}.fits" where "{Identifier}" denotes the unique identifier of an image. See the study for further details.
./Cal_Star_Images_fits_Mar30_2023_L2_Early_Release
LICIACube LUKE RGB FITS images of the Pleiades and Chi-2 Ceti that were used to perform a calibration of the LUKE absolute responsivity for the study.
./Plume_Source_Images_fits_Mar30_2023_L2_Early_Release
During flyby, the LUKE RGB camera aboard LICIACube acquired a sequence of images at approximately 3 s cadence. Images in this archive were those used for the study where the plume was largely within the field-of-view, and target distance was < 200 km.
