APEX data archiving

All ESO and Swedish APEX data are stored in the ESO archive. The archive can be searched using the APEX instrument specific query form. These data follow the standard ESO archive rules, i.e. they become publicly available 1 year after they have been delivered to the principal investigator of the project. Both the raw MBFITS files and the combined CLASS files per project are stored in the archive. However, note that for heterodyne data, the MBFITS files are of limited use, as one needs access to the Calibrator software, which only runs on the local APEX machines. For LABOCA, the calibration data from all APEX partners and the host country Chile are also publicly available.

A decicated page on APEX Science Verification is also available. This page contains the publicly available data and information on the projects.

The APEX weather station and radiometer measurements are available from the APEX Weather Query Form

We request that any publication using APEX data, including the public science verification data, adds the following acknowledgement as a footnote after the first mentioning of APEX in the body of the text: "This publication is based on data acquired with the Atacama Pathfinder Experiment (APEX). APEX is a collaboration between the Max-Planck-Institut fur Radioastronomie, the European Southern Observatory, and the Onsala Space Observatory.
