Cropping a solar map in sky coordinates

The public work

The example loads a SWAP solar image, defines crop corners with SkyCoord in the map’s coordinate frame, and displays the cropped region with a solar limb and coordinate grid.

What to notice

Carry coordinate frames and angular units into the crop request instead of treating sky coordinates as interchangeable pixel offsets.

Keep the context

A crop of a supplied observation, not a new solar finding. Coordinate-frame agreement and observation metadata matter; the displayed script timing is not a transferable performance benchmark.

AI use: Not reported in the source.

The inspected source does not report AI-assistant use by its authors.

A useful public example is not an assessment of a reader, a publisher or a Better Loop member.

Use material you are allowed to work with. This suggestion is preparation; it does not record a completed task or an improvement.

A prompt to adapt privately

Using a local copy of the sample map, reproduce the coordinate-based crop and annotate its frame, units and bounds. Compare the crop with the full map, then deliberately supply a mismatched-frame practice input and explain how your validation catches or resolves it.

A check to adapt

The crop bounds map to the requested region in the stated frame; metadata remains traceable; mismatched coordinates are detected or explicitly transformed.

Partial pooling for Minnesota radon measurements

The notebook joins Minnesota household and county data, fits pooled, unpooled and hierarchical radon models, and displays posterior diagnostics and comparisons. The partial-pooling plots show how estimates change with county sample size.

Selecting peaks in a recorded ECG signal

The SciPy example applies height, spacing, prominence and width conditions to a recorded ECG segment. It displays selected peaks, interval arrays and property values, making each filtering choice inspectable.
