Surrogate for Particle-based model

This file contains the surrogate needed to fit the bivalent Particle-based model to bivalent SPR data. Further information can be found in our manuscript "Huhn et al, The molecular reach of antibodies crucially underpins their viral neutralisation capacity".<br>

本文件包含将二价基于粒子的模型拟合至二价表面等离子体共振（SPR, Surface Plasmon Resonance）数据所需的代理模型。更多详细信息可参阅我们的手稿《Huhn等人：抗体的分子伸展程度是其病毒中和能力的关键基础》，该手稿的英文原标题为 "The molecular reach of antibodies crucially underpins their viral neutralisation capacity"。
