The ALMA Re-Imaging for Legacy Project

The ARI-L project is an European Development project for ALMA Upgrade approved by JAO and ESO that officially started in June 2019. Recently, the ARI-L project completed successfully its first year review, with the reported activities well ahead of schedule. The first 60000 science FITS files have already been ingested into the official ALMA Science Archive.

The project aims to increase the legacy value of the ASA by bringing the reduction level of ALMA data from Cycles 2-4 close to the level of the more recent Cycles processed with the ALMA Imaging Pipeline. In three years, the ARI-L project will produce and ingest into the ASA a uniform set of full data cubes and continuum images at native spectral resolution and average weighting scheme, covering at least 70% of the observed data from Cycles 2-4. These cubes and images do complement the much smaller archived QA2-generated image products, which cover only a tiny fraction of the available data for those Cycles. The complete set of ARI-L imaging products will be highly relevant for many science-cases and significantly enhance the possibilities of exploitation of archival data.
