I just thought of something I wasn't sure of and as it might be to help I thought I might post it here.
If I would send a probe to 500/500/50, and it's scan radious is 10 sectors. Will it scan from 490/490/40 to 510/510/60? If not how does it work then if you send a probe to 500/500/50 and it has 10 sectors radious( or any different example, this is just the easyest).

It scans in a sphere in 3D space... I don't know how to say this another way.

I understand, but I need to know which coords it were to scan. So from my example, if it's sent to 500/500/50( doesn't matter what probe) and it's scan radious 10 sectors what will it scan, from where to were. This would help me out a lot for planning better where to send different kind of probes.

I beleive that if it's a radius, then it would be



490/490/40 - 510/510/60



If it was a measuring diameter it would be


495/495/45 - 505/505/55


the x,y,z axis are the x/y/z.. so if you just imaging a graph printed on a sphere were 500/500/50 was the centre.. the y axis would be from top to bottom.. the higher you go up from 500, the more up the y axis you go.. the same goes for the x axis and the z axis... it's just like a graph however the z makes it 3D.

Therfore, if a Radar (which is basically what the Deep Scan is) has a radius of ten, it can go ten metres forward, ten metres back in the x axis, ten metres forward, ten metres backward in the y axis, and 10 metres forward, 10 metres back in the z axis.

And there you have it. I can't think of it any other way.

Scan radius adds 10 sectors on every axis.
So from 500/500/50 you would get data from 510/510/60 and from 490/490/40.

Either this is incorrect or my probes are bugging. I currently have a DSP (5 scan radius) @ 504/504/54 and it is not picking up the BH. I originally tried 505/505/55 thinking it would pick up 500/500/500 through 510/510/60 but this also didnt pick up the BH. So my thought was that it only reads the sectors in-between so the actual coords of 500/500/50 and 510/510/60 were not being scanned and it was LITERALLY only reading the "in-between" sectors.. So I resent a DSP to 504/504/54, to no avail..

I would really appreiciate it if someone with proven information could explain to me exactly how a probes scan radius works. Does it only read things that are within the specified sectors, or what? Like does a DSP @ 500/500/50 read sectors 495/495/45 through 505/505/55 OR can it only pick up signatures that are within 5 sectors away; like a fleet 505/500/50 or 500/500/55 or 498/498/49? I could really use some clarification on this.

i will test that , it can be a math function issue (round function)

no, it works correctly.

but you sent your probe too far away from the black hole.
a 3D-sphere around 500/500/500 doesent contain 504/504/504

Sorry if I am a little slow here; but, that doesnt exactly explain how the 3-D radius works.. Math was never my strongest subject. Is there some sort of formula that makes calculating this easier?

a distance in 3d is calclated like this:

d = sqrt { (x1-x2)^2 + (y1-y2)^2 +(z1-z2)^2 }

in your example:
x1=504 x2=500
y1=504 y2=504
z1=54 z2=50


d = sqrt { 4^2 + 4^2 + 4^2 }=sqrt {48 } =~ 7 sectors

when in doubt ... use the traveltime calculator (sub link of fleets)
