ALICE数据发布：对HST-NICMOS冠状动脉造影图像的重新评价
ALICE Data Release: A revaluation of HST-NICMOS coronagraphic images
摘要：
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。
英文摘要：
The Hubble Space Telescope (HST) NICMOS instrument has been used from 1997 to 2008 to perform coronagraphic observations of about 400 targets. Most of them were part of surveys looking for substellar companions or resolved circumstellar disks to young nearby stars, making the NICMOS coronagraphic archive a valuable database for exoplanets and disks studies. As part of the Archival Legacy Investigations of Circumstellar Environments (ALICE) program, we have consistently re-processed a large fraction of the NICMOS coronagrahic archive using advanced PSF subtraction methods. We present here the high-level science products of these re-analyzed data, which we delivered back to the community through the Mikulski Archive for Space Telescopes (MAST) http://dx.doi.org/10.17909/T9W89V . We also present the second version of the HCI-FITS format (for High-Contrast Imaging FITS format), which we developed as a standard format for data exchange of imaging reduced science products. These re-analyzed products are openly available for population statistics studies, characterization of specific targets, or detected point source identification.
