heal.abstract	A dimensional analysis is carried out for the caustic equations expressed in terms of the Muskhelishvili complex potential. It is shown that, for the infinite cracked plate under mode I loading conditions, the caustic dimensions, appropriately normalized, depend on a single overall parameter that includes the crack length. The formulation presents itself for a straightforward investigation of the problem with respect to the derived parameter and a complete numerical analysis is carried out. The predicted values for the commonly used characteristic dimensions of caustics, obtained from the exact theory and its singular term approximation, are compared. The expected errors for a singular term evaluation of measurements are also presented in convenient single curve plots and may be used as ''add on'' corrections. The errors predicted were found to be from non-negligent to rather appreciable in the region near the crack tip where experiments are ''often'' conducted, as had originally been alleged but was later disputed.	en
