-6 h < hour angle < +18 h (telescope East of pier)
-18 h < hour angle < +6 h (telescope West of pier)
There are no explicit declination limits.
The fully-lowered windshield which sits on the dome lintel sets
a further limit. Because of the asymmetry of the telescope, the
limits are different east and west of the pier (see La Palma
Technical Note 28).
Hour angle and declination: 1.0 degrees/s
Dome rotation: 1.5 degrees/s
Pointing accuracy: RMS residual of a global fit < 15 arcsec
(unguided) < 1 arcsec in 3 minutes; < 3 arcsec in 10 minutes
(guided) < 0.3 arcsec
Rotator positioning: < 0.2 arcsec over the whole field
