Abstract: The currently ongoing Calar Alto Legacy Integral Field Area (CALIFA) survey is aimed to observe ∼600 galaxies in the local Universe (0.005<z<0.03). It is the largest survey to date using optical integral field spectroscopy. Here, we shortly introduce the main characteristics of the survey and discuss a few important steps related to the calibration of the data, focussing on the spectrophotometry and astrometry. Error estimation is always needed for a proper interpretation of astronomical data, so CALIFA will provide proper errors associated with the data. However, all CALIFA users need to be aware of the correlated noise that is unavoidable present in the data as we highlight at the end. We find that the overall quality of the data is excellent for all the core CALIFA science goals, but we are already prepared to increase the accuracy even more for future data releases.
