Ideal aperture-scaled limiting magnitude
Gain=5log10(new/reference); same throughput, sky and observer.

Assumptions & limits
Assumptions & limits
- Relative ideal comparison; not an absolute prediction of faint-object visibility. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints.
