All 10 tagged channels obey a positive conservative hot/cold transport operator with separately inventoried trapping and absorbing boundary loss.

Spatial abundance ratios refer only to injected material; no ambient gas, calibrated cloud population, terminal yield, field survival or observational significance is inferred.",
