rsensor and LICOR LI-210 photometric sensors

Has anyone simulated these in rsensor? Would you care to share your sensor files?

&, if not, any suggestions as to how to write one? What resolution would be appropriate. LI-COR's data informs me that these are "cosine-corrected" sensors, up to 80° off-axis, after which the LI-COR is vague about the response, which seems to falls to zero in some unspecified way.
