Table 1.

Model parameters of the SLD profiles shown in Fig. 1. Scenarios (I) and (BI) in Fig. 3 were used to describe the HBM after incubation with 2776SH. Values of adjusted parameters are shown in italic. Parameters printed across columns were determined by requiring that they fit the respective datasets simultaneously
