Pier/Tri-Pier and DDM85 Dome Slaving Metrics for 2.7m Observatory

[DeepSkyMan]

Hi there, just wondering if anyone happens to have a set of DDM85 metrics that I could use with my 2.7m dome ASCOM setup.  New to dome setup so I'm sort of experimenting at the moment.  As I don't yet have my pier (unforeseen budget complications),  I'm currently working with my Altair Starbase Tri-Pier.  The ASCOM dome setup requires the following in either inches or mm

Total North/South Offset  

Total East/West Offset  

Total Up/Down Offset  

Dome Diameter or   

Dome Radius  

GEM Axis Offset  

Any assistance greatly appreciated.

Kind Regards

Paul.
