Worldsheet (0,2) gauged linear sigma models are often used to study supersymmetric heterotic string compactifications with non-trivial vector bundles. We make use of supersymmetric localization techniques to determine their one-loop partition functions. In particular we derive conditions to ensure that the full partition function is modular invariant and we propose a computational method to determine the target space matter spectrum.
