2 configurations are studied for run 13 (engineering run) where 3 sectors out of 10 will be installed

A. Patch Triangle

Modification of upgr15 geometry in starsim to keep only 3 ladders in the inner layer and the corresponding (matching phi angle) for the outer layer.

The inner layer has 10 ladders and the outer layer has 30 ladders.

The matching between ladder Id, azimuthal angles and (x,y) positions are printed here

The new geometry is shown below : 

B. Patch joined

The new geometry is shown below : 

C. real run 13 configuration.

Neither the SSD nor the IST will be un run 13.

To have a same configuration, disable in /pams/geometry/geometry/geometry.g the SSD (SISD65) and IST (ISTB00)

replace [exe UPGR15;] with ["New Tracking: HFT+IST+TPC+SSD-SVT"
