MPG hosts an archive of raw data of the 100 m Effelsberg telescope, one of the largest steerable radio telescopes in the world. Data observed with APEX are archived at ESO and in Bonn, again in MBFITS and for spectroscopic data also in CLASS format.
At present the Effelsberg archive and the Bonn APEX archive is only possible manually and with support of the institute staff. Within the ACME development, a better access procedure to the data archive as well as automated calibration of the observations of both telescopes via software pipelines will be implemented.
