Our 2D LASNEX simulations of Nova's nine symmetry scaling data bases r
eproduce the fundamental features seen in the experiments. In particul
ar, we predict how we must change Nova's beam pointing in order to ach
ieve best symmetry with various pulse shapes. This need to change poin
ting with different pulse shapes is the result of a bulk-plasma-induce
d migration of the laser deposition/x-ray production region. We have o
bserved and modeled this migration.
