3. German ARC node/Bonn, Cologne Major current activities: User support (including CS, QA2, f2f) Community Training/Outreach (Community Days, hands-on workshops, lecture series, tutorials) Expansion of the Cologne Database for Molecular Spectroscopy XCLASS (CASA toolbox for spectral line identification and fitting) CASA tools for the combination of single-dish and interferometric data Integration of polarization tools into CASA Funding: Federal Ministry for Education and Research, 3-year cycle, last renewed in July 2014 (currently 5 postdocs + IT) Universities of Bonn and Cologne

4. German ARC node/Bonn, Cologne Future perspectives: Maintain current staffing level Maintain special expertise and involvement in development projects as added service to the community New area of expertise: mm-VLBI with ALMA (with MPIfR, EU-ARC) Expand training opportunities for broader astronomical community Issues/concerns: German constitution does not allow federal agencies long-term funding of science support structures at universities (under review) o Funding specifically for development projects/German community o Risk of brain-drain at end of each funding period o additional lines of funding important Additional comments: ES phase proven very useful for training staff, testing procedures etc. German community seems to prefer formal meetings/workshops over individual face-to-face visits
