  4. centerline
    a leader line that runs perpendicular to the set line from the midpoint or center of the opening of the proscenium
  5. instrument schedule

  14. throw distance
    how far light from an instrument travels from its hanging position to the center of its focus area
  15. working sectional
    a drawing showing the sectional angle for a lighting instrument; used to determine its trim height; not to be confused with the lighting section

    a command to take some type of action involving lighting, usually, to raise or lower the intensity of one or more instruments
