N2 - We compare the common-reflection surface (CRS) and multifocusing (MF) travel-time move-out correction for curved reflectors, and clarify the role of the focusing parameter in MF. The MF formula can be designed to be exact for planar and spherical reflectors. For strongly curved reflectors, the planar multifocusing formula is remarkably accurate, but for increasing curvature the CRS becomes increasingly inaccurate. As a consequence, it may be inferred that CRS is less suitable for diffractions.
