We have agreed to remove the azimuthDirection field from trackTarget command of ATMCS and make the azimuth and rotator angles absolute in TPC-163. This ticket is to update the XML and the ATMCS Simulator.

The ATMCS will also have to be updated.

One question: which is indirectly related:

• Should the azimuthCalculatedAngle field of the mountEncoders event be in the range 0, 360 or -270 to 270? We should make sure that the XML has the correct information.

MTPtg and MTMount should probably get the same treatment, but on a different ticket. Whether we actually do it depends on what the MTMount vendor says (they may have already coded it this way!).
