Finding the Telescope Pole Offset - with Tpoint

If a Tpoint model has already been constructed with several stars, the polar offset value is in the Tpoint model file created as in Section 5.3. The ID value described in Section 5.5 is the declination axis offset in arcseconds. To use this value as the telescope pole offset for two-star pointing, simply divide ID by 3600. For the prototype (3a) telescope this is around ${-3.9^\circ}$. Each telescope will have a different value because this number depends on the precise location of the dec axis homing limit switch.
