| dc.description | The data consist of two machine readable tables, with headers that describe the format of the data. The positions table lists the X and Y (row and column) pixel where the boulder is observed in each image where it is detected. The photometry table gives the brightness (irradiance) of a boulder in a 3-pixel radius in each image where it is measured, along with the uncertainty in that measurement. The brightness is normalized to a spacecraft range of 57.63 km (the LICIACue close approach distance). | |
| dc.description.abstract | This data collection contains tables that provide measurements of the positions and brightnesses of meter-sized boulders that were ejected when the Double Asteroid Impact Test (DART) spacecraft crashed into Dimorphos, the moon of asteroid (65803) Didymos on September 26, 2022. The measurements come from the LICIACube Unit Key Explorer (LUKE) instrument on board the LICIACube spacecraft that flew by the Didymos system about 3 minutes after the impact event. The positions table provides the pixel locations of each boulder in the images where it was detected, while the photometry table gives the brightness for each boulder in each of the images where it was measured. | |

- Description:
- Machine readable table containing the position measurements for boulders detected in LICIACube images of the Dimorphos ejecta field. Each row represents a specific boulder, while each pair of columns represent the X and Y pixel location for that boulder in a given LICIACube image. The header information specifies the image number for each pair of columns.

- Description:
- Machine readable table containing the photometry measurements for boulders detected in LICIACube images of the Dimorphos ejecta field. Each row represents a specific boulder, while each pair of columns represent the irradiance and its uncertainty for that boulder in a 3-pixel radius aperture in a given LICIACube image. The header information specifies the image number for each pair of columns. Each brightness measurement is normalized to a common spacecraft range of 57.63 km (the LICIACube close approach distance).
