- Baseline Deviation
- In psychology it is a standardized assessment score with a clinical-cutoff annotation; in normative systems it is a behavior flagged as departing from a published rule; in astronomy it is a transient detection — a brightness reading flagged as deviating from a stellar baseline.

The paper supports difference imaging against a reference frame as the way to detect variable objects, which covers the astronomy example only; psychology and normative-systems examples are not in it.
“photometry and detection of variable (including moving) objects should be based on the dif- ference between frames”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
