UNRESOLVED / OA-F04
The central light source holds a fixed position. The surrounding field does not.
No edit boundary is present in the recovered headers.
A single viewpoint cannot produce both fields. A cut would leave a boundary. Neither condition is satisfied by the evidence.
Three readings have been proposed and none has been eliminated: instrument error, an unrecorded second pass, or a property of the subject.
This record exists to keep the question open, not to close it.
Status: unresolved. Revision invited.
