coronagraph-comparison SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

coronagraph-comparison from peterwar/agentic-eclipse-library is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add peterwar/agentic-eclipse-library/coronagraph-comparison@git:20261027.83da390

Pins git:20261027.83da390 in mdr.lock. Pin the fingerprint instead.

Compare eclipse observations with K-Cor, SOHO/LASCO and SDO/AIA using independent solar geometry, angular-structure nulls and correctly separated brightness measurements.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Compare with coronagraphs

Read [setup and operating instructions](../../docs/USAGE.md) before running AEL. Resolve this plugin's root from this skill file and use its bundled launcher. Respond in the user's language. Work on user-selected inputs and write new output directories.

Read [the package guide](../../docs/README_AEL.md), [field lessons](../../docs/FIELD_LESSONS.md), and [the comparison template](../../examples/coronagraph_config_template.json). Detailed instrument guidance is in [coronagraph-method.md](../../docs/coronagraph-method.md).

Establish which question the data can answer:

- Structure: compare angular detail in separate solar frames, with orientation checks and null rotations. A good correlation after radial normalisation does not measure brightness or exclude every local artefact.
- Brightness: requires linear, sky-subtracted, extinction-corrected and photometrically calibrated data with uncertainty. A JPEG, filtered layer or display composite cannot be treated as mean solar brightness.

How to install

The exact contents, by fingerprint

mdr add peterwar/agentic-eclipse-library/coronagraph-comparison@sha256:a99256664a2df11a

The line at the top of this page pins the label git:20261027.83da390, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
