I don't get the whole "jump shadow" concept as it's been presented.
Every planet... heck every asteroid has its own 100d jump shadow and the farther out from its primary the longer it will be between the departure system and the target system.
Depending on the angle of the departure system above/below relative to the destination systems plane of the ecliptic even small planets like earth could cause lots of fun "shadows".

It simply demonstrates that sometimes you can't just go out to the 100D limit and jump to your destination. As you can see from the demo, for much of the year one has to go a long way from Earth to gain a Jump trajectory to Barnard's system.
The Red dot represents the point where, a ship leaving from Earth, can initiate a jump to that system...

actually still kind of isn't "accurate" (you have a better word?) because it says "is at an angle to the ecliptic"... basically Barnard's star is above or below our plane of the ecliptic.F33D said:
Basically it misses the point that one can fly "up" (or down) in relation to the ecliptic - to the same side of the ecliptic as Barnard's star is on, and probably get out of that shadow much faster that what is being shown.
Or in other words.. a 2-d model of very little detail is a very poor way to represent a 3-d dynamic system with any real accuracy.

Unlike subsector maps, of course.GamerDude said:

Wouldn't the ellipse of the shadow be modelling that though Gamer Dude?
As it says in the diagram:
"Shadow is elliptical as Barnard's star is at an angle to the ecliptic."
I'm not saying they have the angle correct (but suspect they do), but an elliptical jump shadow implies an angled vector (out of the plane) between the two, doesn't it? If it were flat (2D) without respecting a difference in the plane of the two systems then the jump shadow would be widening and infinitely long trailing Sol. Or have I missed something?
It looks more to me a case of... a 2-d model with just enough detail is a good way to represent a 3-d dynamic system with enough accuracy for a game. Ditto that for subsector maps too

Incorrect. The model takes into account that angle from our ecliptic so the distance representation IS correct. The jump shadow is ALSO 3D...
Let me put it this way...
A post gives me a direct link to a cute animation that really doesn't give much information at all and is actually just a "top-down" look at the shadow. How useful is that.
now if it were to map out like, the angle a ship would take from the ecliptic (based on the relative position of earth, sun, bernard's star etc) to get out of the combined 100d limit/jump shadow.
The as the animation comes (clockwise) around under the grey area the red "optimum" dot jumps from the bottom to the top edge (makes sense) but doesn't account for going "up or down" as optimal.
Oh and alex_green... all *my* starmaps (including the ones copied from OTU sources) have distances above/below the ecliptic. Makes for a very very different universe when you actually think in 3d. Things like "oh is jump 1 limited literally to 1 light year or is that an approximation" and so forth. I have my in house rules to decide the min/max ranges of jump 1 through 6 are so it works for me.
