BlaST: Synchrotron peak estimator for blazars

BlaST (Blazar Synchrotron Tool) estimates the synchrotron peak of blazars given their spectral energy distribution. It uses a machine-learning algorithm that simplifies the estimation and also provides a reliable uncertainty estimation. The package naturally accounts for additional SED components from the host galaxy and the disk emission. BlaST also supports bulk estimation, e.g. estimating a whole catalog, by providing a directory or zip file containing the seds as well as an output file in which to write the results.
