I use a Kinect 360 and wonder if my statictransformpublisher values for the transform from the base_link to my kinect are right?!

The kinect is 28 wide, and looking at my kinect, coming from the left:

• the position of the laser beam lense is at 8 cm,
• the position of the RGB color lense is at 13cm and
• the position of the depth lense is at 15cm.

Which point of the kinect or which lens I need to transform to?

At the moment I am simply transforming to the exact middle/width-center of the kinect, between the RGB and depth lenses at 14cm. Is that correct?

Note: My static transform from the baselink is x=11cm, z=5.4cm and y=0 as the foot of the kinect is exactly alligned to the center of baselink.
