Horizon events use a 10° mask; the filter applies to maximum elevation. Passes are predictions, not scheduled recordings.

02 / RECEPTION ARCHIVE

Every capture has a story.

Original observations, with their gaps, products, and source records.

REPRODUCIBLE BY DESIGN
01

Receive & preserve

Original CADUs and processing logs remain intact. This portal copies selected evidence without changing the source archive. Raw IQ is retained separately on the Pi where documented.

02

Check the frames

Count complete 1024-byte records, distinct records, expected sync markers, and trailing bytes. SHA-256 hashes connect each download to its archived source.

03

Keep the limits visible

Decoded products can contain missing lines. Colour composites are variants of the same observation. Geographic overlays are withheld pending scan-time validation.
