Amit,

There is JzOp which does take a parameter, and Jz is JzOp("J"). The
parameters for the Rotation operator are the Euler angles that define the
rotation. I'm not sure if you need to know anything about the angles or
what parameters are used to modify qapply. You should be able to look at
the Rotation operator test to figure out what the output should look like
for various parameters.
