Condensation efficiency, defined as the mass fraction of atoms locked up in dust grains, of carbon, iron, strontium, hafnium, and platinum in the low-density (upper) and high-density (lower) cases. Note that the dust formation of Hf and Pt in the high-density case is unlikely because low f_i (≲ 10⁻²) is required for r-process elements in GRB 130603B.
