Spectral Stacking Data for Phase 1 Science Release of GOTHAM

<p>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.</p>

<p>
A link to the collaboration website can be found <a href="https://greenbankobservatory.org/science/gbt-surveys/gotham-survey/" target="_blank">here.</a>
</p>

<p>
The data is organized as folders for each individual molecule, which includes three files:
</p>

<ol>
<li> A serialized NumPy array containing spectral chunks of the TMC-1 survey </li>
<li> A README detailing the parameters used for the stacking </li>
<li> A catalog file containing model frequency and intensity information generated using SPCAT.
</li>
</ol>

<p>
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.
