Super-SNID: An Expanded Set of SNID Classes and Templates for the New Era of Wide-field Surveys

Journal article

We present an expanded template library for the supernova identification (SNID) software, along with updated source files that make it easy to merge our templates—and other major SNID libraries—into the base code. This expansion, dubbed “Super-SNID,” increases the number of spectra for under-represented supernova classes (e.g., SNe Ia-02cx, Ibn) and adds new classes (e.g., SLSNe, TDEs, LFBOTs). Super-SNID includes 841 spectral templates for 161 objects, primarily from the Public ESO Spectroscopic Survey of Transient Objects Data Releases 1–4. The library is available on GitHub with simple installation instructions.
