(4) Extracted cores, whose peak position is at worst partly inaccurate, and whose flux measurement is inaccurate by at worst a factor of 2 (see definitions below).

(5) Detected cores, whose peak position is very inaccurate: Θ_{offset-position} > Θ_beam/2.

(6) Detected cores whose peak position is partly inaccurate: Θ_beam/4 < Θ_{offset-position} ≤ Θ_beam/2.

(7) Correctly extracted cores, whose flux measurement is inaccurate by at least a factor of 2, or > 2. These sources are not considered correctly extracted cores (see Col. 4), and as such are excluded when estimating completeness levels in Fig. C.1.

(8) Correctly extracted cores, whose flux measurement is inaccurate by a factor between 1.5 and 2, . Roughly detected cores generally have rough measurements.
