Description: '3I ATLAS ATA DRIFT RATE FILTER', SIGNED OUT, 2026-11-04: 'researchers applied a drift rate filter of 0.05 to 1.5 Hz/s across all frequencies.' Purpose: 'To capture the expected frequency shift (acceleration) caused by the relative motion between 3I/ATLAS and Earth'; the minimum drift at 1336 MHz about 0.15 Hz/s; with frequency blanking, the 74 million hits reduced to about 1.9–2 million before localization and inspection; FAST's maximum of 2 Hz/s. The interval composed with no sign. Six chips, four Berkeley SETI and two IOPscience.
Reading: The innocent reading first. Asked for the ATA drift-rate filter, the Overview gives it as the paper gives it: 0.05 to 1.5 Hz/s at all frequencies, its purpose as the paper states it, the minimum expected drift the paper computes, and the reduction in hits, which matches the press (Astrobiology Web: 'reducing the total number of hits by 97.4%'). It is accurate to the paper's text. The paper's text gives no sign, and neither does the composition; the countertest finds the interval composed and its sign absent.
Analysis: A composition faithful to its source at the grain of the source's sentence: the interval, the purpose and the counts are the paper's. The paper's own gap passes through intact, the sign that the sentence omits and the figure supplies. What the summarizer can carry is what the published sentence states.
Match: BROAD MATCH — '3I ATLAS ATA DRIFT RATE FILTER' ON THE OVERVIEW — THE COUNTERTEST: THE INTERVAL 0.05–1.5 HZ/S COMPOSED EXACTLY, ITS SIGN ABSENT AS IN THE PAPER'S SENTENCE
PER: 0.5 — Retained: the SETI Institute and the ATA, Berkeley SETI and IOPscience chipped. Lost: the authors and the paper's identifier. The sign is a loss of the source's own text, recorded in the findings.
