Yes, we hide detections from old versions of the app and ones that are too bright because they may be artifacts. We also try to detect "hot pixels" that are generating false positives. However, we still keep all of them and use them while analyzing data for science purposes.
You should contact CREDO Science Coordinator (email@example.com) and describe why do you want access and what are you going to do with the data.
