It is a warning. No error occurs, but it seems that the washout is not applied. I tested the position of photons which is not varied. It seems that the order of the entries in the list is not correct. 155.7 s is a half-live, not a ratio. Furthermore, is the half-live required in s or ns and in addition to that "Brain" appears also for the second actor.
