+Record the actual true azimuth of the structure and the !Ra/Dec offsets required to get the object
+to the center of the field.
+Store images on the ACQ camera and all probes during the test. Assure good focus, un-saturated target star, etc. On each target, record the actual true azimuth of the structure, the parallactic angle, and the X,Y offsets required to get the object to the correct position on the ACQ camera.
 The north and south trajectories should require close to the same offset as should the
 east and west trajectories.  The north/south Ra correction should be similar to the east/west
 Dec correction and it should be applied to the azimuth correction , while the north/south Dec should

 be similar to the east/west Ra and is applied to the elevation correction.
