This website holds data related to the paper arXiv:1706.07688, where physically promising heterotic line bundle models were constructed on elliptically fibered CY manifolds with two sections. The 442 line bundle sums found for 6 base spaces are provided as a Mathematica list which can be downloaded here. This file includes help on the type and format of the data provided and can be loaded into Mathematica using the Get[“filename”] command.
