Notes:
Ø
Relative displacements due to the MECO launch event
are not included in the above table.
Ø
The numbering convention for the sixteen trackers is
shown in the following table. Note that tracker numbers consist of two digits.
The first digit stands for the tracker row number and the second digit denotes
the tracker column number. Also note that the CG’s of the trackers in row one
have the highest Y coordinates, and CG’s of the trackers in the fourth column
have the largest X coordinates (in the LAT coordinate system).
