The Additional Representative Images for Legacy (ARI-L) project is a European Development project for ALMA Upgrade approved by the Joint ALMA Observatory (JAO) and the European Southern Observatory (ESO), started in June 2019. It aims to increase the legacy value of the ALMA Science Archive (ASA) by bringing the reduction level of ALMA data from Cycles 2-4 close to that of data from more recent Cycles processed for imaging with the ALMA Pipeline. As of mid-2021 more than 150000 images have been returned to the ASA for public use. At its completion in 2022, the project will have provided enhanced products for at least 70% of the observational data from Cycles 2-4 processable with the ALMA Pipeline. In this paper we present the project rationale, its implementation, and the new opportunities offered to ASA users by the ARI-L products. The ARI-L cubes and images complement the much limited number of archival image products generated during the data quality assurance stages (QA2), which cover only a small fraction of the available data for those Cycles. ARI-L imaging products are highly relevant for many science cases and significantly enhance the possibilities for exploiting archival data. Indeed, ARI-L products facilitate archive access and data usage for science purposes even for non-expert data miners, provide a homogeneous view of all data for better dataset comparisons and download selections, make the archive more accessible to visualization and analysis tools, and enable the generation of preview images and plots similar to those possible for subsequent Cycles.

ALICE Data Release: A revaluation of HST-NICMOS coronagraphic images
从1997年到2008年，哈勃太空望远镜的NICMOS仪器对大约400个目标进行了日冕观测。其中大多数是寻找亚恒星同伴或解决拱星盘到年轻的附近恒星的调查的一部分，使NICMOS日冕档案成为系外行星和盘研究的宝贵数据库。作为星际环境档案遗产调查（ALICE）计划的一部分，我们一直在使用先进的PSF减法方法重新处理NICMOS日冕档案的很大一部分。我们在这里展示了这些重新分析数据的高水平科学产品，我们通过Mikulski Archive for Space Telescopes（MAST）http://dx.doi.org/10.17909/T9W89V将这些产品提供给社区。我们还介绍了HCI-FITS格式的第二个版本（用于高对比度成像FITS格式），该格式是我们开发的用于成像简化科学产品数据交换的标准格式。这些重新分析的产品可公开用于群体统计研究、特定目标的表征或检测到的点源识别。
