Spectral Stacking Data for Phase 2 Science Release of GOTHAM

This dataset contains all of the necessary data to reproduce the spectral stacking discoveries in the Phase 2 data release of the GOTHAM and ARKHAM collaborations, which investigate the role of aromatic chemistry in molecular clouds. A link to the collaboration website can be found here. The data is organized as folders for each individual molecule, which includes three files: A serialized NumPy array containing spectral chunks of the TMC-1 survey A README detailing the parameters used for the stacking A catalog file containing model frequency and intensity information generated using SPCAT. Please note that for datasets besides 1- and 2-cyanonaphthalene and benzonitrile, the supplementary data enclosed are in HDF5 formats instead of the lower level NumPy arrays. To access this data you will need to use h5py or similar library. If you are interested in using this data, please contact Dr. Brett McGuire or a member of the GOTHAM collaboration. When using this data for research, please be sure to cite this Dataverse entry, in addition to two papers that detail the GOTHAM methodology: Loomis, R. A., Burkhardt, A. M., Shingledecker, C.
