The first ARI-L continuum images and data cubes generated by the Additional Representative Images for Legacy (ARI-L) ALMA development project are now available for download in the ALMA Science Archive (ASA).

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 covering at least 70% of the data from Cycles 2-4. These cubes will complement the much smaller QA2-generated image products, which cover only a small fraction (< 10%) of the observed data for those cycles. The complete set of ARI-L imaging products will be highly relevant for many science-cases and enhance the possibilities of exploitation of archival data.

Recently, the ARI-L project successfully completed its first year of activity. The first image products of about 1000 cycle 3 and 4 datasets can now be retrieved from the ASA as "Externally delivered products". Furthermore, all the corresponding calibrated measurement sets are stored on the INAF-IA2 facilities and can be requested with an email to the Italian node of the EU ARC Calibrated measurement sets for these and other projects are also made available by the European ARC through the ALMA Helpdesk (see this link for instructions).
