GBT
Green Bank Telescope clock correction file
This file records the difference between UTC(GBT) and UTC(GPS).
The observatory distributes this file on the Web, updated about daily.
A discrepancy arose between the observatory-distributed file and the file in this repository (which had been identical to the observatory-distributed one up to that point). Around 2023-03-20 (MJD 60023), the first ~11 entries in the observatory-distributed file were changed to zero. Ryan Lynch expressed surprise that this had occurred, but no resolution had arisen as of 2024-02-14. Since this resulted in the new file failing validation and the file in this repository not updating, at that point I (Anne Archibald) decided to switch those entries to match the observatory values. The old values are available from the version of the file in git tag “gbt-mystery-values”.
