Base Signature Strength

Every "Type" of Cosmic Signature has a Base Signature Strength which determines how strongly probes will interact with it. Base Signature Strengths come in a limited set of "bands."

These bands are:

• 1/5 (20.0%)
• 1/10 (10.0%)
• 1/15 (6.67%)
• 1/20 (5.0%)
• 1/25 (4.0%)
• 1/40 (2.5%)
• 1/60 (1.67%)
• 1/80 (1.25%)

Each of the different types of Cosmic Signatures will always have the same base signal strength. This means that a pilot may scan a large group of signatures by setting scanner probes to maximum range and then by comparing the resulting "bands" against known signatures that pilot may discern what each result may be with out having to scan every signature to 100%.

Example

For example, the following scan of the Hasiari system (in high sec) contains 5 unknown signatures.

Scan Signature Signals in the Hasiari System

For this scan, a single Deep Space Scan probe with 9.8 Base Sensor Strength was used: set to its maximum range of 256 AU and placed near the middle of the system. The strength of a scan signal will decrease with distance. Because most systems tend to be less than 60 AUs wide, a probe set to a 256 AU range will commonly have very little variation in signal strength due to distance, allowing signatures to line up clearly into their respective bands.

9.8 Base Sensor Strength

At this probe's 9.8 sensor strength, a result of .37% is in the 1/5 band, the .19% result is in the 1/10 band, the .12% results are in the 1/15 bands, and the .09% result is in the 1/20 band.

At this point there are a number of possibilities for most of the signatures. The 1/5 result could be a drone or a pirate hideout or a small hidden asteroid belt (1/5s never occur in w-space). The 1/10 result could be a number of different things but is most likely to be a K162 wormhole (generic exit), which is the most common 1/10 signature. In high sec, a 1/15 signature could only be an R943 wormhole to class 2 space, and, finally, the 1/20 result could, again be a number of things.

After a thourough scan of the system, we can see the following results.

The 1/5 result is a Sansha Hideout. File:Scan Band Matching 3.png

The 1/10 result is a K162 wormhole. File:Scan Band Matching 4.png

The 1/15 results are both R943s as expected. File:Scan Band Matching 2.png File:Scan Band Matching 5.png

And finally, the 1/20 result is an X702 wormhole. File:Scan Band Matching 1.png

Uses

The real power of this technique comes when a pilot is looking for a specific signature who's strength he knows. He may simply scan the whole system once, and ignore any results which do not fit into the band of the signature for which he is looking.

In w-space (a.k.a. Anoikis), this is a particularly powerful technique because signatures fit into a very rigid signature strength scheme:

• All "Perimeter" Ladar and Grav Sites are 1/10
• All "Frontier" Ladar and Grav Sites are 1/20
• All "Core" Ladar and Grav Sites are 1/40
• All w-space Radar and Magnetometric sites are 1/40

Wormholes

For each class of w-space, there is a limited set of wandering wormholes which may appear in it, and every system has only one static wormhole (class 2 systems have 2 statics). Once the Base Signature Strengths of each of these wormholes is known for the given class of w-space a pilot is in, pilots may easily narrow down which signature is their local static or another type of local wormhole. A full listing of nearly all wormhole signature strengths is available under the List of All W-Space Systems.

*Publication on psudo-statics to come soon... until then, see this post.
**I suspect there was an error in the original data or the signature strengths have changed: all wormholes in the 1/80 band should probably be in the newly discovered 1/45 band.
***M267 should probably be in the 1/20 band and E175 in the 1/25 band
****B041 might not form in high sec or is exceedingly rare: see Project Snapshot
This is a product of Project Atlas.

Some helpful hints for scanning these bands in Anoikis:
Class 1, 3, 5, and 6 wormhole systems have one static wormhole which is native to that system, and these systems may also see a number of wandering wormholes with various bands.
Class 2 and 4 systems have only static wormholes.
All classes of wormholes will see many K162s which are always in the 1/10 band.
A pilot who knows the possible wormholes which may appear in the system he's currently scouting, can speed his search for exits.
Keep in mind, that a given system will only commonly see one static type, but from time to time an "extra" static type wormhole might appear (these are currently under study by Project Atlas and are theorized to be Constellation Statics).

Signature Band List

A complete listing of all Cosmic Signatures' Base Signature Strengths is in production, and will hopefully be available soon.

Signal Drop-off

Base Sensor Strengths tend to vary with the scanner's skill, and different sensor strengths will give slightly different results, with stronger probes giving stronger results. There is a formula for figuring out what strength results will have, but pilots' experience with their own probes is usually sufficient. For this technique, core scan probes could also be used, but when using core probes the maximum distance is 32 AUs, so it should be kept in mind that the observed signal strength will diminish significantly with distance. Thus, signatures on the edge of a scan may appear to belong to a different band. This can be dealt with by taking multiple scans centered at the various groups of planets in a system and using the strongest results for each signature.
