You can do EPSGetBV() and then BVGetColumn() for each of the first nconv columns. But this has risks, for instance the BV may contain Schur vectors instead of eigenvectors, or separated real and imaginary parts in case of complex eigenvectors in real arithmetic, an possibly other solver-dependent issues.

What is the use case for this?
