Similarly to effective parameters, interval parameters can also be
regarded as data attributes obtained from local slopes. Unlike the
-
domain, the
-
domain offers us several alternatives to
conventional Dix (1955) processing for retrieving interval values.
In this section, we analyze three different options for extracting
interval parameters in the
-
domain.

Table 1. This table lists the inputs required to retrieve
both effective and interval VTI parameters as data attributes obtained
from local slopes. The zero-slope time
function is always
required to map the attributes to their correct position in
time. Processing data in
-
domain offers two more alternatives
than conventional Dix's processing in
-
domain. Moreover, we observe
that Fowler's is the only set of equations that does not require an
explicit use of the curvature.
