Refer to Acquistion:

The indicator helps tell you how many the nearby allies are close enough to give you their affinity when killing. (Within 50 meters of you.) This is also useful for some abilities that apply allies within a certain range.
 * Be near an allied Tenno when they kill an enemy. When within 50 meters of an ally when they kill an enemy, you gain the same total Affinity, split according to your own weaponry. This doesn't reduce the Affinity gained by the killing player, and doesn't reduce the Affinity gained by other nearby allies. This does not apply to Archwing and the Interception mode; they have much larger ranges for shared affinity.
