Lines are well fit by our four parameter model (b is actually held constant at b=1; so three free parameters): z PupÕs X-ray lines are consistent with a spatially distributed, spherically symmetric, radially accelerating wind scenario, with reasonable parameters:
t*~1        :4 to 15 times less than predicted
But, the level of wind absorption is significantly below whatÕs expected.
And, thereÕs no significant wavelength dependence of the optical depth (or any parameters).
