The data aggregating and plotting code of Galaxy Zoo: 3D

• make_subject_fits.py: This code uses the panoptes-python-client to grab and aggregate the classifications for a point drawing workflow, a polygon drawing workflow, and a poly-freehand drawing workflow. All classification data and resulting pixel masks are stored in a .fits file.
  • The output of the point aggregation is any cluster of points with more than three classifications within 5 pixels of each other (using DBSCAN). The center and 2-sigma extent of each cluster is found and a pixel mask is created for these ellipses.
  • The output of the polygon and poly-freehand aggregation is a pixel mask a count of the number of classifications that contained that pixel. It also ignores any self-intersecting polygons (as they don't have a well defined "inside").
• mpl_style.py: A custom style file for matplotlib
• plot_fits_files.py: This code takes the .fits files created above and makes plots showing the various pixel masks
