CX / FIELD COPY / QUALIFICATION

SCHEDULE

COMMON WITNESS · SEATING OF RETURNS
USE WHEN SEATING A RETURN AGAINST A NAMED WITNESS.

This schedule does not establish witness identity. Apply after identity has been carried from the prior interval. One field division is 73 common seconds.

1 / EDGES

  1. Sound the lesser edge at named depth.
  2. Hold the second return. Count the third return as an edge only when its remainder is pale.
  3. Do not correct zero. Zero belongs to the prior interval.
