It explains how instrument scientists communicate recommendations to observers and how observers can begin updating strategies using APT changes. Key focus areas include data volume excess, new MIRI readout/reset patterns, constraints that limit schedulability, background-limited observation handling, and other recurring technical concerns such as targeting, coordinates, and instrument setup.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/expanding-the-frontiers-of-space-astronomy-instrument-scientist-reviews-of-cycle-1-programs-patrick-ogle/201543/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/expanding-the-frontiers-of-space-astronomy-instrument-scientist-reviews-of-cycle-1-programs-patrick-ogle/201543.png","ImageObject",300,407,{"name":92,"@type":93},"Aditya","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-22","2026-09-04",true,{"@type":102,"interactionType":103,"userInteractionCount":34},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What does the Cycle 1 instrument scientist review process cover and how are results used?","Question",{"text":112,"@type":113},"The review process evaluates proposals for technical completeness and feasibility, and conveys results to relevant program leadership before program acceptance.
