  "abstract": "<p>This repository contains the data released in the paper &quot;Galaxy Zoo DECaLS: Detailed Visual Morphology Measurements from Volunteers and Deep Learning for 314,000 Galaxies&quot; <em>(DOI to follow on publication).</em></p>\n\n<p>We release detailed morphology catalogues, both volunteer and automated, for Galaxy Zoo DECaLS.</p>\n\n<p>- gz_decals_volunteers_ab contains volunteer classifications for galaxies classified during the GZD-A and GZD-B campaigns.</p>\n\n<p>- gz_decals_volunteers_c similarly contains classifications from the GZD-C campaign. Note that GZD-C used a modified schema designed to better detect mergers and weak bars, and includes many galaxies with only approx. five volunteer responses.</p>\n\n<p>- gz_decals_auto_posteriors contains the predicted posteriors for volunteer responses to all galaxies used in any campaign, recorded as Dirichlet distribution concentrations.&nbsp;</p>\n\n<p>- gz_decals_auto_fractions reduces those posteriors to the automated equivalent of previous Galaxy Zoo data releases; the expected vote fractions (mean posteriors). Note that not all vote fractions are relevant for every galaxy; we suggest assessing relevance using the estimated fraction of volunteers that would have been asked each question. <em>In the v0.0.1 release, these are included within the gz_decals_auto_posteriors files.</em></p>\n\n<p>Each catalogue has a schema of the same name. <em>These are not yet included in the v0.0.1 release.</em></p>\n\n<p>We also release the galaxy images shown to volunteers on www.galaxyzoo.org. The images on which the automated classifier was trained may be derived from these volunteer-facing images. These are not yet included in the v0.0.1 release.</p>\n\n<p>We will release updates if needed via Zenodo versioning. We recommend using the latest version of this repository. You can check the version you are currently viewing on the right-hand sidebar.</p>\n\n<p>Please cite the paper (DOI to follow on publication) when using the data in this repository.</p>",
