I'm getting almost half-way through my slice. Something that's mildly annoying, but not really unexpected, is just how far off the in-game systems can be from the catalog locations. I sorted the list by catalog distance, and in the game the distances are quite randomized, only "generally" following the distances. Since I'm trying not to delete my bookmarks, I'm only able to bookmark 10-20 of these at a time, and some are a distance away and I won't get to them for a while. So this is causing me to do a lot of zig-zagging and only hitting a few at a time. But, it's keeping me moving, which suits me well. ;)

I did notice that when comparing the estimated distance to the "plane" in the spreadsheet to my estmates from the galmap, that they werent too far offf numerically, but there is no indication in the ss as to whether they are above or below the galactic plane, So many coordinate (y?) distances have the wrong sign. This might account for the zigzagging.

You can see if they are above or below from the galactic latitude - I only used the absolute value on the estimate to make it easier for conditional formatting. :)

With respect to distances in general I think there's many sources of discrepancy - the distances given on the sheet are SIMBAD's estimates based on the parallax values in the HIPPARCOS data, but that is not particularly accurate. Moreover, I'm not sure where the original ED placing of the stars drew its distances from - they could be from HIP but possibly from elsewhere too. In general it's really hard to measure distances to stars without good parallax - you need to make a bunch of assumptions. Direction is easy, distance is hard, so you can't trust anything that says "star such-and-such is 1025 ly away" - a corollary of that is that you also can't trust size estimates, so also don't trust anything which says "these are the biggest known stars, this one is such-and-such times bigger than the Sun." Although with the recent GAIA data there are now a lot better estimates of position, but that's not in game... maybe Elite 5. ;)

(Ok, that's a little unfair - you can trust things to be somewhere in the ballpark for distance and size and whatever, but not to the extent that you might at first think, even for obvious things - the distance to the Pleiades is an example.)

Yeah, I was just mildly surprised at how much of a "random" variance ED appears to have relative to the catalog distances, but yeah definitely, there's no way to know which sources of parallax distances they gave precedence to.

Just for clarity: Sorted by distance from Sol and working my way inward, it's generally been moving me in the right direction, but with each star that I bookmark, it could be a couple thousand lightyears nearer/further from Sol than its neighbors in the sorted list, making almost a random pattern within the slice as I add them and then work through them. The trend has still moved inward, but take any 20 of them with adjacent distances, and they definitely will not look at all like a nice fuzzy curved "wall" within the slice. Rather they're spread out over several thousand lightyears in distance from the bubble, and many of the "further" stars can turn out to be a good 3k closer to Sol than some of the "nearer" stars. ;)

I ran into the same problem when I first started. Using the distances from Wikipedia I'd end up bouncing all over the place. I ended up culling almost all my bookmarks so that I could plot everything out before I started.

I detoured to check out HD 106863 - I'm seeing the same behaviour. Now back on track at HD 118674, which was previously unknown to EDSM and is now known, so it looks like there's just a problem with HD 106863.

(Or it could be Raxxla. On ne sait jamais!)

Also - nothing in the system was tagged at all, it will be interesting to see what happens when I sell up.
(eta - that went fine so no problems with the system in-game at least)

I haven't turned in the data yet, I was the very first one there so all untagged as you say, but it appears to be a an issue with third party software because if you check your in game logs all is good there so it may be an incorrect id64 in the EDSM database as you say.

I bookmarked as many as I could that were marked as a long way, then started taking slices up and down through the galaxy to get around 20 a time and add more bookmarks, there are still a few that appear far behind me but I will leave them for my next pass with the FC to get the really high and low ones.

It sounds like you folks have plans for this.

I'm just wandering about willy-nilly (although I have swapped the eagle for the dolphin to speed it up slightly)

What is it they say about plans during war? A good plan lasts as long as the first engagement, that's usually how mine work for everything, I make a plan to go to X and before I get there I've been around the galaxy twice. I shall stick with this one as long as possible 🍻

I ran in to this oddity earlier:

HIP-71672-say-what.png


The system is around 650 ly from Sol, and appears to be completely deserted. I haven't been able to find "J.Co" or "The Consultants" as a minor faction; the text implies it's a player group rather than one of the systems that have had a description from the start. Anyone recognise them?

HIP-71672-in-context.png


Tried a few transpositions but no luck;

HIP 71672 - out in the boondocks, listed as (player?) faction "J. Co" or possibly "The Consultants"
HIP 71627 - out-Bubble, uninhabited
HIP 71762 - redirects to empty space near ADS 9338 AC
HIP 76172 - not found
HIP 17672 - out-Bubble, uninhabited

That's definitely weird!
As you say, it looks like a misplaced PMF judging from the text.

Edit:
What's in the system? I don't see the description when I search it.

Whilst visiting HD 124170 (HIP 69274) in sector 14 I unexpectedly came across HIP 67396, which is not in your spreadsheet (at least I couldn't find it).
I just had a quick look at the main HIP catalogue and it is there, but I couldn't work out whether it is in the correct position.
It is 219ly from HD 124170 and contains a class B primary, a class A secondary, but nothing else.

Just thought you'd like to know.
