SolO/EUI Data Release 6.0 2023-01

The Extreme Ultraviolet Imager (EUI) is part of the remote sensing instrument package of the ESA/NASA Solar Orbiter mission. The EUI consists of three telescopes, the Full Sun Imager (FSI) and two High Resolution Imagers (HRILYA, HRIEUV), which are optimised to image in Lyman-α and EUV (17.4 nm, 30.4 nm) to provide a coverage from chromosphere up to corona. EUI scientific data consists of calibrated and raw data images acquired by the three EUI telescopes. Following the orbit profile of Solar Orbiter, the data coverage, imaging cadence and effective spatial resolution of the EUI data are very variable. "SolO/EUI data release 6.0" was initially released with the Solar Orbiter/EUI data up till and including 2023 January ??. Later data will be included a-posteriori in this release as long as the software (including calibration) remains stable that generates the science data products.

极紫外成像仪（Extreme Ultraviolet Imager, EUI）是欧空局（ESA）与美国国家航空航天局（NASA）联合实施的太阳轨道器（Solar Orbiter）任务遥感仪器载荷的组成部分。EUI包含三台望远镜：全日面成像仪（Full Sun Imager, FSI）以及两台高分辨率成像仪（HRILYA、HRIEUV），上述设备针对莱曼-α（Lyman-α）谱线与极紫外（EUV，17.4 nm、30.4 nm）波段成像进行了优化，可实现从色球层到日冕的全范围观测。EUI科学数据由三台EUI望远镜获取的原始数据图像与定标后数据图像构成。随着太阳轨道器的轨道运行特性变化，EUI数据的覆盖范围、成像观测频次与有效空间分辨率均存在显著差异。“SolO/EUI 6.0版数据发布”最初随截至2023年1月？？的太阳轨道器/EUI数据一同发布。只要生成科学数据产品的软件（包含定标流程）保持稳定，后续数据将以事后补录的方式纳入本次发布版本中。
