I knew about p118 before asking, actually, but;
Quote from StratOps, p118
The controlling player makes a Detection Check with a +2 modifier,
as well as an additional modifi er equal to half the distance from
the arriving JumpShip/WarShip in AU (1 AU is approximately
150 million kilometers).
Its a standard jump point - Let's assume an Aquila and a Star Lord jump to the same zenith jump point.
Quote from StratOps, p118
Apply a further modifier by subtracting the incoming unit’s full
K-F Drive integrity + its DropShip capacity, divided by 10, to
generate a final modified target number for the Detection Check.
Round all fractions up at each stage.
Yes, I know that since P-JS carry their Dropshuttles internally, they don't make it easier to detect. What I meant to ask was, to put it a different way;
If I make a smaller Jump (say, 15 LY) is the emergence wave of a smaller Jump harder to detect?
Or, for example, is an Aquila harder to detect than a Star Lord
(WITHOUT DROPSHIPS) given the Aquila is smaller (the Aquila is only about 36% the size of the Star Lord)?
The impression I got is that the Scout and the Hunter are fluffed to possess a yet smaller jump signature than their relatively small size and single hardpoint would suggest anyways, to the point of being especially notable. However, there are no special rules for this, and no quirk I'm aware of.
Much like the Scout's quicker-than-normal recharge cycle, or the Merchant's slower recharging.
Well - I guess maybe handwavium, then? I realize the wave is caused by the sudden imposition of matter on the stray dust and particles when it arrives at a Jump - I had hoped there might be some military benefit, but since the volume of the JS will be the same regardless of whether it Jumps 15 LY or 30 LY it seems unlikely.
For the Explorer as it has no docking collars it has no emergence wave.
Seems unlikely given the explained cause. So, is size (volume) important in casting a small emergence wave, then?
