    Looks like the Noijou sector where I scanned every body in the 350 odd AA-A H systems.
    Huh. I had thought I was responsible for that cube with... I'm on the wrong computer to look, but I think Fleasoae. They're neighbouring sectors, I think.

    I'm about to spend quite a bit of time in the vicinity. I located an AA-A H system with gas giant helium content in excess of 30%, which I've never found before, and now want representative sample scans of all of the G and F boxels in the sector. I'm trying to find patterns in object distribution between mass codes, and gas giant atmospheric content is one area where I've found some possible evidence supporting interrelationships.

    Looking at the data for the "top" of the galaxy, not taking into account scanned stars, my EDSM data has 43 systems above +3000 ly:

    Mind if I ask where you got the database? I'm in the process of learning the limitations of spreadsheets and want to see an example of a sql database that's already populated with some ED objects.

    I downloaded JSON dumps from here: https://www.edsm.net/en/nightly-dumps

    And then built the database from that with some custom multi-threaded scripts that parse the JSON, and then decide whether to update or insert based on what's already in the DB.

    I decided to colorize the black holes green. Everything else I was trying to make the colors at least somewhat reasonable to what they actually are, but the BHs are impossible to see that way, and this makes them stand out. Also I thought it would be interesting to make a graph of star distribution based on distance from the galactic plane:

    Wow, this is awesome! I tried to +Rep and it told me I need to spread around the love, so I guess there's something else you've done that I also liked a great deal. Keep up the great work CMDR!

  6. #36
    This is all great stuff +1 Vrep ...
    I presume the densities will be distorted by the fact that we will 'seek out' BH and NS.

  7. #37
    Glad you like it! Thanks

    Yeah, the entire image is skewed by CMDR scanning habits, so that's something that has to be kept in mind while looking at these. It's more a measure of that, than the actual star distribution.

    Since this came up separately elsewhere, I'm also now rendered supernova remnants (black holes and neutron stars) in a separate map (click for full size):

    This is some supreme goodness right there ! Can't rep you enough for this !

    By any chances, would you have a version of the HR diagram focusing on Wolf-Rayet stars ? For science of course !

    Cmdr Redfox made one:

    SO many black holes and WR stars, yet I have only come across a couple of BHs in some 15K LYs of travelling!

    What is the reason of gaps at x=0 and y=0 and three layers visible on vertical view? Problem with data presentation?

    Quirkiness of the StellarForge. There are gaps in where certain star types are generated in the procedural generator.

  14. #44
    Speculation wrt to the suppressed star types along the X=0 and Z=0 was/is twofold:
    a) there are sufficient manually authored systems around the bubble, so the FD's plan was to suppress certain proc-gen star types in the area around the bubble
    b) while programming the suppression of the two axis an "OR" was used instead of an "AND", resulting in two suppressed lanes instead of one suppressed area

    The "Misc" category includes things like S-type stars, MS-type, CN-stars, etc.
