Detailed Description

This (clean) interface is implemented in the (rather dirty) ICaloCoordinateTool class, which depends on data-bases and H8 CTB specificities.

The goal of these classes is to handles the translation between :

• the H8 CTB official coordinate system, defined in :

  "Atlas Barrel Combined Run in 2004, TestBeam Layout" ATC-TT-IN-0001, Beniamino Di Girolamo

  All variables in this coordinate system contain the letters _ctb

• the LAr+Tile local coordinate system, which differs for 2 reasons :

  the origin is shifted by x = 2298 mm, and the two calos sit on a rotating table to allow eta scans.

  In the local coordinate system, calorimeters have a pointing geometry.

  All variables in this coordinate system contain the letters _local.

  • All intermetiate variables contain the letters _table. They are not meant to be used or known by the public interface.

Most clients are only interested in the methods ICaloCoordinateTool::ctb_to_local and ICaloCoordinateTool::local_to_ctb, which convert a given point from one coordinate system into another. The read_table_position() in called internally, is is transparent to the user.

But Atlantis clients need access to the AmgTransforms used internally. Some public methods are thus provided. Note that, for these methods, the user has to call read_table_position() before hand.
