Description [src]
Evaluates the derivatives of the logarithm of the filtered variance at lnr and z, namely:
- $n = 0 \rightarrow \ln \left[ \sigma(r, z)^2 \right]$,
- $n = 1 \rightarrow \frac{\mathrm{d}\ln \left( \sigma^2 \right)}{\mathrm{d} \ln r}$,
- $n = 2 \rightarrow \frac{\mathrm{d}^2 \ln \left( \sigma^2 \right)}{\mathrm{d}(\ln r)^2}$,
- $n = 3 \rightarrow \frac{\mathrm{d}^3 \ln \left( \sigma^2 \right)}{\mathrm{d}(\ln r)^3}$.
