RGBD Extrinsic and Translate

Hey guys,

I have done the Calibration and got thes Matrix.

[Left Camera Intrinsic]
639.889 0 438.408
0 682.699 238.665
0 0 1
[Right Camera Intrinsic]
581.121 0 398.877
0 613.3 235.588
0 0 1
[Right to Left Camera Rotate Matrix]
0.999103 0.000654995 0.0423347
-0.000276567 0.99996 -0.00894418
-0.0423389 0.00892445 0.999063
[Right to Left Camera Translate]
-27.1772 0.304922 6.79525

now i want these with the ROS OpenNI package for my ASTRA S

So i have tryed to make the yaml files like in
http://wiki.ros.org/ccny_openni_launch

but it is inpossible to find an example of extr.yml:

or how i can start open NI with the new Rotate Matrix or Camera Translate but i need to because i have an offset in my depth image and the HW registration has to may artefacts
