fieldA field is a part of a camcol that is processed by the Photo pipeline at one time. Fields are 2048x1489 pixels; a field consists of the frames in the 5 filters for the same part of the sky. Fields overlap each other by 128 rows; primaries are decided when Chunks are resolved (using objects between rows 64 and1425 as primaries). A field at the edge of a Chunk may in fact be included in 2 (or more) Chunks.
