Abstract

The quality of scientific data depends on the accuracy of the absolute intensity calibration. This absolute calibration is especially difficult in ground-based sub-mm astronomy. At the Atacama Pathfinder Experiment (APEX), we take various measures in order to ensure a proper calibration of the final science product, including real-time efforts (e.g. pointing models) and dedicated measurements whose results are applied afterwards (e.g. opacity or efficiencies). In this presentation we will give an overview over the various steps taken at APEX to overcome most calibration challenges. We will explain their implementation as calibration plan, present an analysis of the results obtained, and discuss those results in view of the reliability of the released science product.
