Table 1.
Degree of asymmetry: 0 = none, 1 = mild, 2 = moderate and 3 = severe.
Perfect agreement is expressed as frequencies on the diagonal. Disagreements regarding degree of asymmetry are expressed as frequencies in non-diagonal cells where increased distance from the diagonal indicates stronger disagreement. Frequencies in areas outside four by four blocks indicate a photograph was judged as skewed one time and flat the other time.
