Anyone that gets a Lay on hands from a Paladin also gets all the effects of the Paladin's Mercies. As the Channel Positive Energy uses two lay on hands do they also get the effects of the Mercies?
Quote from Pathfinder SRD:
Whenever the paladin uses lay on hands to heal damage to one target, the target also receives the additional effects from all of the mercies possessed by the paladin.
Using lay on hands to channel energy is clearly not the case.
