The goal of the upgrade, which uses a new SAPHIRA detector with sub-electron readout noise, is to add at least two magnitudes to the limit for the wavefront sensing while simultaneously increasing the correction rate to 500 Hz. The 500Hz Small-Scale mode of the new IRLOS system is in operations with a fully automated acquisition since the beginning of Period 107 with a limiting magnitude of J=17.0<sup> </sup>for point sources. This fainter magnitude limit is offered for P108 and DDT observations during P107. Prior to this commissioning MUSE Narrow Field Mode could use as AO reference stars brighter than H=14.5, with the sensing done at a fixed 200Hz with field-selector scales for point-sources, SmallScale, and extended objects, LargeScale.</p> </div> <div class="read_more_link" align="right"> <a href="https://web.archive.org/web/20210416194347/https://www.eso.org/sci/publications/announcements/sciann17401.html">Go to Announcement</a> </div> <div class="clear"></div> </div> </div> </div> <div class="pr_box"> <div class="pr_lead"> <div class="pr_list_image"> <a href="https://web.archive.org/web/20210416194347/https://www.eso.org/sci/publications/announcements/sciann17400.html" target="_top"> <div style="background:center no-repeat url(https://web.archive.org/web/20210416194347im_/https://www.eso.org/sci/publications/announcements/sciann17400/_jcr_content/abstract/image.img.png/1618575915357.png);background-size:contain;width:122px;height:92px"></div> </a> </div> <div class="pr_list_text"> <h2 class="pr_headline"> <a href="https://web.archive.org/web/20210416194347/https://www.eso.org/sci/publications/announcements/sciann17400.html">ESO Science Archive: 10,000,000 Processed Science Files Downloaded … and Counting!</a> </h2> <strong>Published: 16 Apr 2021</strong> <div class="teasertext"> <p>March 17<sup>th</sup> marked an important milestone for the ESO Science Archive with the download of the 10,000,000<sup>th</sup> processed science file by a member of the ESO community.
