Module ring 

Canonical 16-sample rings used by the ChESS detector.

Enums

RingOffsets

Valid ring radii and their canonical offset tables.

Constants

RING5

16 point ring offsets. Order is clockwise starting at top. This is the FAST-16 pattern scaled to r=5 and rounded, matching the paper’s “radius 5, 16 samples” design.

RING10

Optional heavier-blur ring (same angles, r=10)

Functions

ring_offsets

Get the 16-sample ring offsets for the requested radius.
