This adds the latest_asmap.dat result for the coordinated launch from #40 for epoch 1767888000. We had a match from 7/9 participants in the coordinated launch.

The sha256 hash after encoding the file are:

  • filled (encoded with --fill) / latest_asmap.dat: 95badecc3d0490d25e6fba1babf2b4ce3e9694fd867646330941fa390a0a0a86
  • unfilled 11f8515a4eb0a0a6f515806d777581a9160abcf3de5e5c353d04d9d5de9d724c
    To confirm the result of the encoding you can use asmap-tool.

I reproduced the same encoded maps from my result file and verified that the files added here match those that I produced.
