Collimators positions display on DIP- TCDD- TCDIH- TCDIV- TCLA- TCLIB- TCP- TCSG- TCTH- TCTVA- TDI

Distance in millimetre with respect to the beam orbit which coincides with the collimator centre;

For the coordinates system please refer to the following slides.

Collimators apertures:- for all collimators except TDI: min gap ~ 1mm; gap max ~ 60mm;- for TDI: min gap ~ 3mm; gap max ~ 120mm.
