Data Set Overview
=================
This data set contains raw images of the LICIACube target, asteroid
system composed by (65803) Didymos and its secondary Dimorphos, 
taken during its science phase. The observations were
made using the LICIAcube Unit Key Explorer (LUKE)
wide field RGB camera, at a resolution varying 
up to 4.3 m/px. 
Scientific results can be found in Dotto & Zinzi, 2023, DOI: https://doi.org/10.1038/s41467-023-38705-0.


Parameters
==========
The images are supplied as 8-bit, unsigned-byte, per pixel FITS files.  
Observational parameters for each image are incorporated 
into the PDS labels and FITS headers supplied with
the data.


Processing
==========
The following description was extracted from the lcc_leia-luke_sis.pdf SIS document,
urn:nasa:pds:liciacube:document:lcc_leia-luke_sis.
Additional details are in the SIS.

All observations are raw data reported in Digital Number. 
Additional information includes: integration time
time of acquisition, observation geometry and relevant housekeeping 
data. 


Data 
====
Images are supplied as FITS files with headers produced by
the ASI-SSDC LICIACube SOC processing software, with detached PDS labels generated by
ASI-SSDC LICIACube SOC.

The images (in DN) are contained in 8 bit per pixel 
FITS files. In addition, the FITS header contains UTC date and start time, exposure time, 
and a series of other keywords described in the SIS.

The pixels contains red, green and blue values following a standard Bayer filter 
(details are provided in the SIS).

The FITS keywords referred to quaternions are not valid for data acquired on Sept. 26 2022
(i.e., during the autonomous tracking phase of the S/C), as the correct S/C attitudes has been
evaluated a posteriori and stored in the dedicated SPICE kernels.

The FITS keywords referred to CORT_UTC and COTJDAT have accuracy ranging from 0.5 to 1 seconds.

Confidence Level Overview
=========================


Data are in raw format, the only conversion applied 
is the conversion from packet telemetry to FITS format.
All the images are in digital numbers without any conversion applied.
