David, it's probably a typo. The 6 is above the 9 on the standard keypad. Fat fingered it all the way.

You called it - I had not previously realized it, but found a graphic making it clear that the entire structure pivots to aim the telescope, sunshield and all (except, I would guess, solar arrays and antenna).
The Ka-Band, high-gain antenna is biaxial steerable (two S-Band omni-directional antennas are not steerable). The solar arrays are fixed at a cant angle = 30°(midpoint of the range of pitch angles).
