Finished! Looks like this project is out of data at the moment!
The tutorial and field guide have been updated. A new dataset has also been loaded.
FAQ
Please read the tutorial and the Field guide before starting to classify.
Q: All of Sci, Ref, Diff images look blank. What shall I do?
A: Skip. it is due to a bad stretch, often due to the presence of a bright star. There may or may not be a real object at the center. The team will look at the skipped objects at a different stretch, and to understand other reasons why the object could have been confusing.
Q: I see many objects in the difference image. Which one should I be grading as real or bogus?
A: Only the one in the center of the image. Ideally, there should not be multiple sources in the difference image but sometimes there can be somewhat suboptimal subtractions.
Q: Is there a test we can take to see if our classifications are correct?
A: Coming soon. Meanwhile, take a look at the discussions in the 'Notes' and validate your thoughts against those examples.
