Pos err | Position error (arc minutes - see note below) |
All co-ordinate values are epoch J2000. These values have either been taken directly from ADC sources or have been calculated from earlier epoch values.
A position error value represents the difference between the co-ordinates known to the LX200 and the current values due to the precession of the Earth's axis of rotation. Most values are small enough to be of little concern.
