With reference to the "Diagnostics for Conservation at Müstair Monastery" project (DIACOMM, mol_1) with Dr. Patrick Cassitti in charge (IPERION HS 2nd call for access to MOLAB of 01/02/2021 closed on 30/06/2021 and with notification for access to the user of 10/09/2021) are reported by followed the results obtained from the geophysical survey.

The GPR data weed using the Sir 3000 georadar system (GSSI) with the 2GHz, and 900MHz antennae along grids with parallel profiles set 0.1 m apart for the 2GHz and 0.25m apart for 900MHz. Data were acquired by the Laboratory of Geophysics of the Institute of Heritage Science (National Research Council) team. The team was composed by Dr Vincenzo Di Fiore (ISPC Napoli), Dr Ivan Ferrari (ISPC Lecce), Dr Daniela Tarallo (ISPC Napoli), and Dr Michele Punzo (ISPC Napoli).
