2D Filtering Operations

Filtering in the (k1,k2) domain, and the (F,K) domain is often useful for changing dip information in data. The programs

• SUKFILTER - radially symmetric K-domain, sin2-tapered, polygonal filter
• SUK1K2FILTER - symmetric box-like K-domain filter defined by the cartesian product of two sin2-tapered polygonal filters defined in k1 and k2
• SUKFRAC - apply FRACtional powers of i|k| to data, with phase shift
• SUDIPFILT - DIP-or better-SLOPE Filter in f-k domain

provide the beginnings of a set of K-domain and F-K-domain filtering operations.
