HAM2 Picomotor Channel List:

From our capacitance measurments (LHO: alog 14148), and the cable specification drawings: D1000581  and D1101515, we concluded that the picomotor on HAM2 are connected to the following channels:

Channel        Picomotor

1                     ISS (PM1-closer to the array)

2                     IM4 Transmission QPD 

3                     Faraday Half Wave Plate

4                     IMC Input Pointing

8                     ISS (Before the telescope) 

5, 6, 7             Empty

This is consistent with the channel assignment at LLO alog 12174

During the process we moved the Faraday HWP (Channel 3) and IMC Input Pointing (Channel 4) quite a bit, but we brought it back to its original position, atleast on theory. We moved these the same number of steps back as we moved forward and viceversa. :)
