Field notes
The interface combines a target map with chunks from the public Breakthrough Listen archive and runs the drift search in the visitor’s browser graphics card. Its stated reference test is Voyager, alongside two other published hits; each chunk covers 1,048,576 channels and 837 drift rates. The page also acknowledges an archive limitation: several named targets cannot yet be sliced because they are stored in a compressed format.
