In Linz, Kepler's primary responsibilities (beyond completing the Rudolphine Tables) were teaching at the district school and providing astrological and astronomical services.
Linzis oli Kepleri põhikohustus (peale "Tabulae Rudolphinae" lõpuleviimise) õpetamine provintsikoolis ning astroloogiliste ja astronoomiliste teenuste osutamine.
