quick observation..

The layout of the columns is a "constellation" that looks like the little dipper... same basic layout, number of stars, curve of handle

If so, the H column is the odd one out, and if you look for an interesting star around there, I find a syzygy of k Cephius & HIP 99169, tho distance away isn't quite right. Or maybe HIP 92738

Also note that stars come up in the symbology for F column, which is speculated to encode spectra, maybe from stars

I'm reminded of https://en.wikipedia.org/wiki/Kryptos

My introduction to most of these ciphers has been through DEF CON puzzles over the last 20 years. This is a fun way of seeing them presented to the world.
