# Not committed: together they are about 38 MB, and a checksum pins a file more
|
|
# precisely than a copy of it does. The date is when the checksum was taken, so a
|
|
# later mismatch can be told apart from a transfer error. Tab-separated; read by
|
|
# both the fetch script and src/kernels.rs, so there is one list rather than two
|
|
# that can disagree.

# NAIF's earth_latest_high_prec.bpc is deliberately NOT used. "Latest" is not a
|
|
# thing a reproducible result can cite, so the dated snapshot covering the same
|
|
# span is pinned instead.
