For a detailed Finder Chart and rotation setting see Kyle Kaplan's software. For rough rotations use the lookup table below.
133 193 = Default Encoder Setting at 90 deg. PA (slit east to west)
Position Angle (Start north and go east, N=0, E=90, S=180, W=270 degrees, Default = 90 deg slit oriented east-west)
(Encoder Setting) = 133 193 - 90 + (Position Angle) = 273 103 + (Position Angle)
WARNING: We recommend you do not rotate the instrument more than +/- 90 degrees from the nominal 90 degree position to avoid entangling wires and hoses. The
The encoder setting limits are:
| Positon Angle | Encoder Setting |
|---|
| 0,180 |
