CoachA raw capture is the sequence of bytes received at a capture point, kept without interpretation, each unit (a packet, a frame) with the time the firm received it.

Example 2.4 (A field nobody kept)
The simulator’s executed-with-price messages (type C) carry a printable flag that says whether the execution counts toward the day’s volume, and its order additions carry the instrument’s symbol and a tracking number. The normalised record has no field for any of them. A researcher who later wants volume that excludes non-printable executions can recompute it only from the raw capture; from the normalised store, the information is gone for every day already written.
