FITS files - Statistics

The table below shows the number and the accumulated size of Alma Science Archive FITS files whose sizes are above different thresholds for each year since 2011.

Artemix provides access to all the FITS files until 2016 (red columns) with no limit on size. From 2017 on, only files with sizes <2 GB are stored on ARTEMIX. Larger datasets can be retrieved interactively.
