OK, I have it added to the website:

https://edastro.com/mapcharts/files/shortest-rotation-planets.csv

This is the 1000 shortest rotational period planets, with details. Assuming I did this right, it should show the actual period in the file, but is building and ordering the list based on the absolute value.

Mostly off-topic but I have a hunch that you might be able to answer the following question since this seems to be more of a database than actual data question: why appear odd numbered ID64's almost double as often in the EDSM bodies data compared to even numbered ID64's?
It might not be the case any longer, but I've checked this for more than 1 year old data.

If I had to guess...

IIRC the least significant three bits of the ID64 are the layer of the stellar forge octree a system is in (i.e. 0=A through 7=H). Lower mass systems are far more common than higher mass. BUT, mass code A systems are mostly worthless brown dwarfs and such, so outside the bubble many people have those filtered out. Thus I'd guess the most common mass code in the database is B=1, which is odd. Then on top of that, people specifically hunting ELWs etc usually focus on mass code D=3 systems, which is also odd.

Orvidius · Dec 7, 2021

Sorry for the late reply, but yeah, I think that's the right answer. The prevalence of mass codes B,C,D, (two odd and one even, with diminishing numbers in that sequence) with people filtering out the low mass stars that mostly make up the A-mass systems, is probably the reason. People who set their filters for only F/G-class stars will hit a lot of D-mass systems too.

Added some organics maps here:

A great thread and very great work! I would like to kindly draw your attention to my communication from some days before.

This map shows you the big 5 streams of EDO-Lifeforms. As you can see, they are oriented towards the galactic arms.

Hi Orvidius, been looking though this list of non-proc stars with no main star listed, and it seems a bit strange;

Glorious HIPs - 3306

I have just updated the new spreadsheet. 384 new names were added. Also updated the spreadsheet for unexplored stars by slice, I gave simplfied this spreadsheet to just show the slice number, HIP and HD names and their approximate coordinates. I am thinking of reviewing the remaining slices...

forums.frontier.co.uk

As you can see from the list there are a few catalogue groups listed, but going through the PSR stars give me some strange results, this group here for instance;

PSR J0218+4232	0	0	19000	-11764.8	-5721.91	-13778.7

I have taken a picture of the location of the highest stars in the group, in the picture are two circles, the lowest yellow circle is actually Rackham's Peak.

There are also some so low they couldn't possibly be reached, and some so far outside the edge of the galaxy they couldn't possibly be reached, do we know how these made their way into the EDSM database? I can only imagine it must have been some sort of dev inspired activity as no player by themselves could possibly reach some of them.

Trilateration.

It's not exactly difficult to feed EDSM with unreachable systems, but most of them might have simply been added by an admin to make them available for trilateration.

Oh yes I know the data can be entered manually, however you have to get the data first, and these are so far outside the galaxy you can't focus on them to get the coordinate data so I can't see anyone except the devs being able to provide it, although I do note that entering these systems into the EDSM search comes up with no data at all now, not sure where the data is coming from in the data dump in that case. As I said, the whole thing is strange.

It's possible to get to those systems in the GalMap (at least in Horizons). The game moves to them, sees that they are too far away to be displayed and moves back. But there's a short time frame in which in the distance to that system is visible, so if you capture that moment you can trilaterate those systems.

The jump to and away thing happens in Odyssey also, but first you actually have to know those systems are there!

Eahlstan · Jan 15, 2022

Well, those are catalogue systems. Nothing easier (yeah I know that breathing is easier) than taking that catalogues and checking which systems trigger a reaction in game.

Orvidius · Mar 13, 2022

I'm trying out another pin/marker layer on the interactive map. These are carriers that have had an EDDN docking event within the last 7 days, and are at least 500 ly from Sol and 200 ly from Colonia. Roughly 90% of fleet carriers are within those ranges, and those aren't exploration-relevant since they're in inhabited space. I may tweak the radius and date range at some point, depending on how it goes.

One of the things I have it doing (and this took some creative circumvention of my own scripts) is to consolidate pins when the carriers are within the same map pixel.

This could be very useful information for some cmdr's, and I have no problems with my available services being advertised but obviously some carriers mine included can be on the move a fair bit of the time.

What update interval are you thinking of using?

Orvidius · Mar 14, 2022

It updates once every 4 hours.

EDIT: Oh, I also wanted to add for everyone here-- the docking permissions don't come through on the EDDN docking events. All we know is that "someone" has docked. For that information I need the CarrierStats events, which don't come through EDDN. I only get those by direct submission to the EDAstro API by the carrier owner, which EDDiscovery supports, but you have to turn it on. To do it through EDMC, you'd have to install the IGAU ATEL plugin.

Orvidius · Mar 14, 2022

I've now bumped up the time frame for docking events to 30 days, so it'll catch more carriers that haven't been visited for a few weeks, which happens frequently in the outer galaxy.

Orvidius · Mar 14, 2022

Oh one more thing-- I can also manually hide specific carriers. If any carrier owner wants their carrier taken off the map, I can do that.

You may as well do that for mine, since mine is never open for visitors.

K Olley · Mar 15, 2022

Mine was already turned on, the only thing that does not show and may not be within the reported info is notorious commander access is Not allowed

Friendly Visitors are always welcome on my carrier, The only thing that I wish we had was a visitors log or message board.

OK cool, I just need the callsign (ownership info doesn't come through automatically).
