ARRAY section

There is one ARRAY (= receiver array description) section per frontend-backend combination and per baseband. The following list is for frontend-backend combination 1 and baseband 1 (the corresponding structure names for frontend-backend combination 2 were FEBE2%HEADER1 and FEBE2%DATA1, respectively FEBE2%HEADER2 and FEBE2%DATA2 for baseband 2, and so on).
