Virtual Observation Point (VOP) sets generated using the spectral and Frobenius norm are compared. It is found that while the spectral norm produces less VOPs for a certain over-estimation factor, the Frobenius norm actually produces more accurate VOPs. When compared in terms of sets containing (approximately) equal numbers of VOPs, the Frobenius norm performs better.
