Selected Eigenvalues
 1     2.0000e+00
 2     3.0000e+00

For the selected eigenvalues,
the reciprocals of projection norms onto the deflating subspaces are
 for left  subspace, pl =    3.71e-01
 for right subspace, pr =    6.67e-01

 upper bound on Difu    =    2.52e-01
 upper bound on Difl    =    2.45e-01

Upper bounds on Difl, Difu are based on the Frobenius norm
