Left: histogram of radial coverages of the CALIFA galaxies, i.e. the ratio between the radius of the Field of View of PPak and petroR50_r. This figure does not give the actual spectroscopic coverage, which may be smaller due to S/N issues. Right: histogram of spatial scales with which the CALIFA galaxies are observed. A fibre diameter is 2.7′′, whereas the typical fibre-to-fibre distance is 3′′. The final spatial resolution of CALIFA will depend on future optimizations of the cubing code, but will be approximately 3′′.
