The Correlation object has the following members:

name

A String specifying the repository key.

approach

A SymbolicConstant specifying the approach used in the correlation data representation. Possible values are CORRELATED, MOVING_NOISE, UNCORRELATED, and USER. The default value is CORRELATED.

data

A tuple of tuples of Floats specifying the real and imaginary part of the scaling factor. If approach=MOVING_NOISE, then data represents the noise velocity components 1, 2, and 3.

timeSpan

A SymbolicConstant specifying the time span of the amplitude. Possible values are STEP and TOTAL. The default value is STEP.
