Yeah, I think the Langrange-Capable Stars came out of another thread. We were trying to think about possibilities for where there could be NSPs (notable stellar phenomena) in systems that contain only stars, and no planets. I don't recall if anyone has found any of those yet. But theoretically, Lagrange objects can exist in stable orbits as long as there is a sufficient mass ratio of the two parent objects, and so that's what this spreadsheet is reporting.
It would be interesting to see some charts split out, but the "core" versus "everywhere else" is the difficult part. In some of the maps, you can see a distinct cutoff around the core, but it's very "lumpy" and irregular. So it would have to be fudged with something simple, such as defining the "core" as being everything within 10kly of Sag-A*, for example. But both data sets would be contaminated with each other's data to some degree, because of the weird shapes in those maps. I can put some thought into it though.
Some DW2 heat maps might be cool. Hmm. I can probably make that work, but I'll have to dig through my code a bit. Adding new maps is both easy and tricky, since they all use the same code, and drawn in parallel. I think I can probably add a case where one of them is date-dependent.
