== CMS Forward Pixels Geometry ==
@version 3.02.01 May 30, 2006
@created Victoria Martin
@modified Dmitry Onoprienko
== Subsystem or component described by the file ==
2x3 Plaquette.
== Root volume and its reference frame ==
Root volume : PixelForwardPlaquette2x3Up and PixelForwardPlaquette2x3Down
Y is in the plane of the plaquette, pointing away from the beam line
Z is perpendicular to the plaquette, pointing to the sensor side
== Positioning ==
The file defines AnchorX and AnchorY constants that
correspond to the anchor point (aka active center) coordinates in the plaquette
root volume.
The two root volumes defined by this file contain identical geometry, but differ
in the directions of X and Y axes of the sensitive volume.
PixelForwardPlaquette2x3Up should be positioned unrotated into "PixelForwardPanel3Right" panel,
and rotated by 180 deg around Z into "PixelForwardPanel4Left" panel.
PixelForwardPlaquette2x3Down should be positioned unrotated into "PixelForwardPanel4Right" panel,
and rotated by 180 deg around Z into "PixelForwardPanel3Left" panel.
== Additional comments ==
The volume representing the active part of the sensor is placed with 90 degrees
rotation around Z axis to make its local reference frame Y go along the longer side.
