Detailed Description

Alignment correction for an element of the CT-PPS detector. Within the geometry description, every sensor (more generally every element) is given its translation and rotation. These two quantities shall be understood in local-to-global coordinate transform. That is, if r_l is a point in local coordinate system and x_g in global, then it holds. 

   x_g = rotation * x_l + translation

This class presents an alignment correction to the translation and rotation. It follows these formulae: 

   translation_final = translation_correction + translation_original
   rotation_final = rotation_correction * rotation_original

Alignment corrections can be added, following this prescription: 

   translation_final = translation_added + translation_original
   rotation_final = rotation_added * rotation_original

NB: As follows from the above definitions, all translations are in the global space. This means that the rotations do not act on them.

Besides the values of rotations and translations, this class contains also uncertainties for these paramaters (the _unc data memebers).

The rotation is parameterized by 3 rotation parameters, the matrix is obtained by calling ROOT::Math::RotationZYX(r_z, r_y, r_x), which corresponds to: 

     | 1     0        0    |   | cos r_y  0  +sin r_y |   | cos r_z  -sin r_z  0 |
 R = | 0 cos r_x  -sin r_x | * |    0     1     0     | * | sin r_z  cos r_z   0 |
     | 0 sin r_x  cos r_x  |   |-sin r_y  0  cos r_y  |   |    0        0      1 |

merges (cumulates) alignements match between x, y and read-out shifts is not checked

Parameters
sumErrorsif it is true, old and new alignment uncertainties are summed (in quadrature) if it is false, the uncertainties of the parameter (i.e. not the object) will be used With the add... switches one can control which corrections are added.
