FAQ
Task
How can I tell if a set of tracings is clustered correctly?
If the Tutorial and Field Guide are not able to help you decide if a specific case is clustered correctly or not, use your best judgement. You can click Done and Talk to leave a comment on a specific galaxy for the researchers. Including a hashtag comment (#example) can help group similar galaxies together. You can also create collections of similar cases by clicking the Collect icon at the bottom right of the viewer.
Why do some of the clustered lines look white in color? Is white used as a clustering color?
We do not use white as a color to indicate a cluster. White/gray is used only to show the aggregate tracing image and not a set of clustered tracings. Some clustered lines may appear white when certain colors overlap in the cluster image. For example, if a yellow cluster line overlaps a magenta cluster line, it may appear white instead of yellow.
Is there a way to skip a galaxy and try it again later?
If you refresh the page in your browser, a new random galaxy should appear from those that you have not yet completed. If the galaxy you are trying to skip is the last one in the sample, you won't be able to skip it.
How do I report a problem image or technical issue?
If you run into some kind of problem, the easiest thing to do is create a post in the Help section. You can also add hashtags (#example) to images when you click Done and Talk on a task. This will organize problem cases.
Science
How do I find more information about a specific galaxy or set of tracings?
You can find a galaxy's metadata by clicking the information icon at the bottom right corner of the viewer (see the image below). The metadata for each galaxy includes the Cluster Buster filenames, aggregated information found on HyperLeda, information found on SDSS, the number of clusters in the image, and a sky survey image from the DESI Legacy Imaging Surveys.
