The paper then breaks that down by location, frequency bands, integration time, lines observed, and resolution. They focus on disks in nearby star-forming regions.\n\nIt does a decent job of organizing that information into one place. Anyone who wants a quick sense of what ALMA coverage exists for nearby star-forming regions can look here instead of running their own archive search. The call to use the archival data is also straightforward and useful. It highlights how much data is already public.\n\nThe soft spot is that everything hinges on the archive query being correct. The abstract gives the number but does not spell out the exact search parameters, how they handled multiple executions on the same target, or how they assigned the science category. If those steps have any ambiguity the 3933 figure could shift. There is also no attempt to do any science with the data, just the summary statistics. No new insights into planet formation come out of it.\n\nThis kind of paper is mainly for observers who need to know the state of the ALMA archive before writing proposals. It does not advance planet formation theory or present new measurements. I would still send it to peer review. A clean, well-documented archive summary can save the community time, and the referees can check the query details. The stress test note is right that there is no load-bearing theoretical claim here.","headline":"This is a straightforward archive summary that counts ALMA observations in one category but adds no new science.","tokens_in":2244,"tokens_out":370,"would_cite":false,"duration_ms":16425,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"grok-4.3","headline":"ALMA has observed 3933 independent coordinates in the disks and planet formation category as of early 2026.","keywords":["ALMA","protoplanetary disks","planet formation","archival observations","submillimeter astronomy","star-forming regions","spectral line surveys"],"falsifier":"A complete re-examination of ALMA proposal and execution data showing that the true number of unique coordinates in this category differs by more than a few percent from 3933.","tokens_in":2530,"feed_emoji":"🔭","tokens_out":551,"duration_ms":17105,"temperature":0.7,"pith_summary":"The paper compiles statistics on all ALMA observations assigned to the disks and planet formation category during the array's first 15 years of science operations.
