Scientific Results

Due to the expertise developed by the L1PP team during previous and ongoing phases of the L1PP, it is now in a position to contribute to the actual advancement of the understanding of the instrument and the mission. Therefore, one of the activities to be carried out through out the project is to perform different studies in cooperation with External Support Laboratories (ESLs).

The following studies are available:
