System security: Difference between revisions

True Security: corrected false information (systems with negative truesec show up as such in the in-game map)

A given system's security level is actually a real number in the range [-1.0, 1.0].  This is known as the system's True Security Level, True-Sec, or Truesec.  It is modified to the value displayed in-game by the following range and rounding rules:<ref name="CCP Explorer">[http://www.eveonline.com/ingameboard.asp?a=topic&threadID=1282632&page=1#4 CCP Explorer forum post]</ref>

* [-1.0, 0.0] = nullsec (always 0.0)
* [-1.0, 0.0] = nullsec
* (0.0, 0.05) = rounded up to lowsec (0.1 security level)
* (0.0, 0.05) = rounded up to lowsec (0.1 security level)
* [0.05, 0.45) = rounded half up (lowsec)
* [0.05, 0.45) = rounded half up (lowsec)
* [0.45, 1.0] = rounded half up (highsec)
* [0.45, 1.0] = rounded half up (highsec)


A system's true security may be desirable to know because nullsec systems may have a truesec range from -1.0 up to 0.0 which continues to affect various game mechanics, such as asteroid belt and rat quality.  A system's truesec value is not accessible by any means in-game, but it is available via the [[official datadump]] or any third-party utilities that use the datadump or the data extracted from it.

This bug has been fixed <ref name="Revelations I">[http://www.eveonline.com/updates/patchnotes.asp?patchlogid=99 Revelations I patch notes]</ref>, and the game now uses the rules above.  This ensures that any system displayed as "0.0" is truly nullsec.  Some third-party utilities may not know of the above rules, and so may incorrectly identify some lowsec systems as nullsec.
