This page contains official mapping  and geometry of FGT strips for one quadrant.

(Strip software ID is not yet assigned)  

Fig 1. assignment of R-strip ID. The Y-octant has index [R001-R280], the X-octant has index [R401-R680].
Indexing has a gap for [281-400], only every 7th strip is drawn,

Fig 2. assignment of Phi-strip ID, index has range [P001-P720], only every 7th strip is drawn.

Fig 3, color denotes AVP chip,  strips served by channel 0 of APV chips are marked (see PDF for details) , all strips are shown

Fig 4 color denotes AVP chip,  strips served by channel 1 of APV chips are marked , all strips are shown

Attachment A  contains full mapping & geometry for all strips in the unified format:

 connectorId[0-9], apvNo[0-9], apvChan[0-127], BenPin[1-1280], plane[R,P], r1(cm), r2(cm), phi1(rad), phi2(rad)

Attachment B,C  show zoom-in of strips served by one connector.

Attachment D contains very short writeup defining FGT quadrant geometry in terms of few constants.   It is used to build the FGT quadrant model in Geant.

Attachment E shows strip indexing (geographical names) and 2D coverage of individual APV chips
