Spectral Stacking Data for Phase 1 Science Release of ARKHAM

This dataset contains all of the necessary data to reproduce the spectral stacking discoveries in the Phase 1 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 into two folders: `catalogs` - Contains catalogs of rotational transitions of benzonitrile, HC7N and HC9N in SPCAT format. `data` - Contains plain-text ASCII (frequency/intensity) of the reduced spectral data used in the stacking analysis. The name of each file corresponds to the target source. Because the spectral stacking was performed on catalogs with hyperfine splitting, the current release of the dataset removes redundant catalogs that do not contain hyperfine components. For non-hyperfine split catalogs, we direct users to the CDMS entries, particularly for the cyanopolyynes. 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: McGuire et al. 2020 ApJL, in revision and Loomis et al. 2020 Nat. Astro., in revision We will update these references as these papers are published.
