Arecibo

Arecibo clock correction file

This file covers clock corrections up to the final shut-down before the collapse. Any updates are expected to be retroactive corrections.

The earliest clock corrections in this file predate GPS and are actually referenced to NIST time directly. Clock corrections from after 1995 are referenced to GPS. This file does not distinguish between the two.

If questions arise, contact David Nice niced@lafayette.edu.
