YieldCurve-

The column titled #YieldCurve- in the table associated with the key Detailsis read-only and contains elements of type Object and specifically subtypes of Yield Curve.
Each element represents the iᵗʰ yield curve YCᵢ⁻ of the yield curve collection YCᵢ⁻, i = 1,...,N produced by a downward shift of the iᵗʰ continuously compounded zero rate rᵢ having the respective maturity.
The bottom element contains the yield curve YC⁻ produced by a parallel downward shift of all continuously compounded zero rates.
