Glorious HIPs - 3306

[Iron Body]

Apologies for the delay in this week's progress report, again.

Of the 386 named stars that Irisa Nyira posted above, 8 of them didn't match entries in the EDSM dump.
The problem is that these 8 stars are in the dump file.

These are the 8 :
HIP 117 : HD 224879
HIP 83988 : Demeter
HIP 3418 : Hathor
HIP 92244 : Algreit
HIP 52549 : Gliese 2083
HIP 30365 : Iansan
HIP 7 : Deeli's Point
HIP 58 : Dieslic

I haven't yet worked out why they don't match.

Edit: HR 4644 is not in EDSM yet.

This would suggest that there are fewer HIPs very close to the plane, which would make sense.

It also suggests that staying either above or below the plane is a good strategy.

Depending on which direction you are going I think!

Dust clouds between us and the core will hide most stars and obscure easy distance measurements directly along the galactic plane, I mean we can't even see the core in visible light so if you are using regular telescopes to try and measure stars you won't get many along the plane towards the core. It would be interesting to compare a slice towards the core and away from the core to see the difference.

Oh yes I looked it up because I was sure I had some screenshots of a previous slice, and here it is, a clear gap at the plane of the galaxy!

Can do ! But I have to finish sorting out this week's merge first. and then get back to bubble to finish slices 52/53 etc... So may take some time.

Edit....

Of course all the current data is in the spreadsheet. Plus, the HIP stars that are not in the current slices (80% of them) should be included as well.

No rush, and while it's true the rest need to be included, most of my slices towards the core including the one I am doing at the moment have very much been the same so that's a good sample of a few thousand HIP's. In fact as I suggested once before I think the natural inclination of observers to target stars outside the galactic plane due to obscuring dust making observation more difficult should apply to a lot of early observations that relied on optical telescopes.

 

[Maelstrom5K]

Halfway through in slices 25 and 26, I had so far way more systems above the plane, than below.
However, that observation could be biased pretty hard, because there are a lot of permit-locked ones in the Col 70 Sector.

 

[Iron Body]

Finally discovered the problems with the 8 stars.
Six of them were in both the named star list and the not found list. Not sure how that happened, probably my fault. And two of them have yet to be visited.
So here is this week's progress report.
I notice that some sectors, notably sector 34, have had small but significant progress, even though they are not yet assigned, afaik.

 

[Iron Body]

The attached graph shows our explored HIP stars looking towards Sag A in red, away from Sag A in yellow.
The sector sizes are not quite equal, so there are more red stars than yellow, as you might expect.
Each small mark is 100ly, the larger marks are at 1000ly intervals.
The x-axis is the horizontal star distance from sol, the vertical axis is distance up or down from the galactic plane.
Sol is the origin, half way up the left edge. So the bubble is the small blob around sol !

I think it does show there is some tendency to avoid the galactic plane in both directions.
Any other artefact is probably a sampling error. For instance there seems to be a lot more yellow stars above the plane, but more red stars below.

Very nice, and I guess it is understandable that there is a tendency to be away from the plane in both directions, dust clouds and other stars wil be far denser along the plane of view than either up or down. That's probably why the furthest stars away from Sol tend to be well below or above the plane, less stuff in the way to impeded ones view.

I notice that some sectors, notably sector 34, have had small but significant progress, even though they are not yet assigned, afaik.

I've come across a few stars in my slices that I am sure weren't listed in EDSM when started but were when I got there, random CMDRS wandering around will probably do that, and if a CG or some sort of exploration event aligns with a certain slice it will probably make a difference. I always check my furthest stars when heading out just in case someone got to them first, after traveling a few thousand LY to a target in one of my early slices and found it already done when I got there I decided it made sense to double check before heading far away from the rest!

Oh, I should have mentioned some were listed as not found, sorry about that.

Gliese 2083 and HR 4664 weren't in my list?

 

[Irisa Nyira]

I've finished slice 23. Can I do slice 39 next?

 

[Iron Body]

That's fine, I'll put your name down for slice 39.

 

[Irisa Nyira]

Thank you.

Found a problem. Might be easiest to explain if I do a table.

Slice	HIP	Name in EDSM	Name in game	X	Y	Z
36	42624	N Velorum	n Velorum	2538.625	-140.75	-169.1875
39	46701	N Velorum	N Velorum	235.6875	-17.21875	35.25

I've raised the type in the name in EDSM on the discord, so hopefully that will get fixed.

Currently the row in the spreadsheet for HIP 42624 is empty, but the one for 46701 has the position for 42624 associated with it.

Yes, it's known that EDSM doesn't distinguish upper and lower case names. EDSM thinks it is a duplicate name.

n Valorum is in EDDB (but not N Valorum) so it should be picked up from there. EDDB names usually take priority over EDSM names in the match process.

I'll add them both to the named star list, and correct the SS.

The last time this happened was with r Carinae, which isn't in EDDB so didn't get picked up at all.
The SS had to be manually adjusted for that one. Which we can do anyway for this one as well if necessary.

 

[Iron Body]

I thought people might be interested to see the current version of my named star list.
It should have been attached to the previous post, but couldn't edit it.

 

[Iron Body]

Star names again - sorry, I couldn't edit the previous post either ....

Anyway, I was looking at this:

List of proper names of stars - Wikipedia

en.wikipedia.org

Which is interesting because many of these RL star names are in Elite, but not all.
Many stars on the wiki list are new proposals so wouldn't have been in Elite anyway.
This could be an interesting project - to find all the real star names in Elite, and visit them.

It may be worth noting that a similar situation happened in slice 43 with E Centauri (HR 4620) and e Centauri (real-life Epsilon Centauri). As expected, EDSM notes it as a duplicate system, but it did not require manual editing because there was no conflict to speak of.

Edit:
Now that I looked into it twice, Epsilon Centauri appears to have the wrong coordinates in the spreadsheet:
E Centauri is at 523.8125 / 138.5625 / 256.6875
whereas
Epsilon Centauri (HIP 66657 ) is at 237.96875 / 69.46875 / 158.6875, but in the spreadsheet it is listed at (321.03125 / 62.28125 / 275.28125)

On the upside (I think), it doesn't appear to be a sorting issue as the in-game coordinates for it are not in the sheet at all.

 

[Irisa Nyira]

I've had a look at Slice 39. I've found 25 more systems with proper names (see named.txt - some of them are duplicate names, so I've included the positions), 53 not found systems (see notfound.txt) and 24 systems that I think are unreachable (see unreachable.txt).

There's just under 200 systems for me to visit.

 

[varonica]

Well on my way back to the bubble now, reaching the area where targets are clusters together, but the first one at the far edge is rather strange, I was expecting a standard G type star and indeed all the stats seem to indicate that, except for the size!

Edit: Oh yes I was just checking the entries on my last run and the Codex actually recorded that star as a G type Giant.

 

[Maelstrom5K]

I've run into issues with HIP 16845 and HIP 47287. Some planets are not added to EDSM although I have scanned or even mapped them. (Yes, I did the EDDN sync.) Those are in detail:
HIP 16845: C3 C4 C5 C6 C7
HIP 47287: A3b A3c A3e A3f
Could someone please visit and re-scan those?


Here are the lists of non-HIP/HD/HR-names stars (first 3 columns are the HIP/HD/HR designations). Let me know if there are still some weird characters.

HIP 36627 - BL Lyncis is the secondary star in the HIP 36626 - VV Lyncis system.

Oh, I should have mentioned some were listed as not found, sorry about that.

Gliese 2083 and HR 4664 weren't in my list?

Although Gliese 2083 is fairly close to the bubble, it doesn't seem to have been visited, or at least it's not in EDSM or EDDB.

HR 4664 is already in the top part of the speadsheet and is completed.

I think you probably meant HR 4644, which is marked as unreachable as well as named, but is actually a long way out and fairly close to the galactic plane, so might actually be reachable. It should be flagged up on the list of unreachable stars <500ly from a known star(*)

Both these stars were flagged as being named and unmatched.

(*) I haven't created that list for some time because of a slight hitch. I assumed that all stars in edsm were reachable. But that's not true, so some stars which were flagged as being within reach might have been in reach of an unreachable star. Which creates a bit of an issue !
