Vortex Catalog from Jovian Vortex Hunter Zooniverse citizen science project

This dataset contains the aggregated results from the Jovian Vortex Hunter citizen science project, where citizen science volunteers labeled images from the JunoCam instrument and determined locations and sizes of vortices.

The CSV file contains results from the first workflow and details the consensus from volunteers on different features in each image (given by the Zooniverse Subject ID). There are five categories to choose from:

1. Vortex
2. Turbulent (i.e. Folded Filamentary Regions: FFRs)
3. Cloud bands
4. Blurry (i.e., image issues)
5. Featureless (there is no discernable feature in the image)

The CSV file also contains an additional column defining the number of classifications of the subject.

The JSON file contains the aggregated catalog of vortices and their properties from the second workflow. The format of the JSON file is as below:

Each entry contains a dictionary of vortex properties, as shown below. The entry is determined by aggregating the vortex properties across multiple Zooniverse images which share the vortex, and building a consensus from multiple volunteer responses.

{
  "subject_ids": [array of Zooniverse subject ID for each vortex],
  "perijove": the perijove corresponding to the image from this vortex was determined
  "color": the aggregated color of the vortex determined from volunteer responses,
  "lon": System III planetographic longitude [degree],
  "lat": planetographic latitude [degree],
  "x0", "y0": reference coordinate on the Zooniverse crop image for longitude/latitude,
  "x", "y": coordinate of the vortex center on the Zooniverse crop image 
  "rx", "ry": radius of the vortex in pixel coordinates on the Zooniverse crop image
  "angle": angle in degree from horizontal of the orientation of the vortex in the Zooniverse crop image,
  "sigma": 1sigma error in the scale of the vortex,
  "angular_width": width of the vortex in degrees on the planet,
  "angular_height": height of the vortex in degrees on the planet,
  "physical_width", "physical width": width/height of the vortex in km,
  "extracts": [ array of dictionaries consisting of individual ellipses that make up the vortex consensus ] 
  "colors": {
    "brown": consensus on the vortex being brown [0-1],
    "red": consensus on the vortex being red [0-1],
    "dark": consensus on the vortex being dark [0-1],
    "white": consensus on the vortex being white [0-1],
    "white-brown": consensus on the vortex being white and brown [0-1],
    "white-red": consensus on the vortex being white and red [0-1],
    "red-brown": consensus on the vortex being red and brown [0-1],
  }
}

Each extract is a dictionary containing the following properties. An extract is a single aggregated ellipse on a single Zooniverse image.

{
  "subject_id": Zooniverse subject ID,
  "perijove": the perijove when the JunoCam image was taken,
  "color": the color of the vortex with the highest vote fraction,
  "lon": System III longitude of the vortex [degree],
  "lat": planetographic latitude of the vortex [degree],
  "x0", "y0": reference coordinate on the Zooniverse crop image for longitude/latitude,
  "x", "y": coordinate of the vortex center on the Zooniverse crop image 
  "rx", "ry": radius of the vortex in pixel coordinates on the Zooniverse crop image
  "angle": angle in degree from horizontal of the orientation of the vortex in the Zooniverse crop image,
  "probability": the 1sigma error in the scale of the vortex,
  "angular_width": width of the vortex in degrees on the planet,
  "angular_height": height of the vortex in degrees on the planet,
  "physical_width", "physical width": width/height of the vortex in km,
