Here are comparable results from OpenSHA. First crossing results were calculated by David Gill, either in UCVMC or python, I'm not sure (but 4.26 files were provided years ago and are thus likely with the C version). Second crossing results were calculated by Scott Callaghan after modifying the python version of UCVM, Summer 2017. Note that the 3rd column is second crossing, not last.&lt;br /&gt;
