These distances are from the center of the player to the edge of the boss's hitring. They should be considered to have +0y, -0.1y accuracy, as the game seems to have a small, but consistent amount of inaccuracy. The vast majority of the time, the boss will actually aggro at ~0.03y closer than the distance shown here, although for some bosses, I have seen as low as 0.09y.
This data does not include cone angles for sight-based enemies. Data was intended for use with primarily bosses, of which all known aggro by proximity, or possibly by true sight with a very wide cone (this would explain anomalies like the e8s blind spot).
One last thing to note: A given BNpc seems to usually have the same aggro distance across territories, but there is at least one case where this does not hold true (ADS in t1 and t2), so it cannot be assumed.
