Selected Eigenvalues
 1   (   2.0000e+00,    1.0000e+00)
 2   (   2.0000e+00,   -1.0000e+00)

For the selected eigenvalues,
the reciprocals of projection norms onto the deflating subspaces are
 for left  subspace, pl =    1.12e-01
 for right subspace, pr =    1.42e-01

 upper bound on Difu    =    2.18e-01
 upper bound on Difl    =    2.62e-01

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