Point brightness

Brightness
Crowd damping — tone down dense clusters

Points blend additively, so a crowded cluster can wash out to white. Crowd damping dims points by how many others land in the same screen patch; brightness is a plain multiplier on top, applied the same to selected and unselected points.

Preselect by Class and Stage

Class: IR spectral index 2-25 µm. Stage: core mass and T★. Buttons set the Class and Stage chips below; chips toggle individually.

Find a model

Brush tool: drag on empty sky to box a group, or toggle Lasso to trace a freeform outline; either stays marked through every view, tracked by star not by screen position. What a new brush does to an existing selection is set by brush action above; shift-drag always adds. Zoom tool: drag draws a box to zoom into, scroll zooms at the cursor either way, Reset zoom restores the auto-fit view. Either tool: click a star to pin it. ←→ views, space tour, d drift, esc clear.

Each view is a linear projection of all properties at once, standardized to median 0 and robust σ 1. Changing view rotates the projection plane, so stars move continuously between diagrams. A star without a value for a property (not defined for that geometry, or no flux at this aperture) fades out as that property rotates in. Fluxes are at 1 kpc.
