class AliFMDSurveyToAlignObjs: public AliSurveyToAlignObjs

 Returns the conversion factor from the measured values to
 centimeters.

 Get named point.   On return, point will contain the point
 coordinates in centimeters, and error will contain the
 meassurement errors in centimeters too.  If no point is found,
 returns false, otherwise true.

 Calculate the plane translation and rotation from 3 survey points

 Parameters:
    a     1st Survey point
    b     2nd Survey point
    c     3rd Survey point
    trans Translation vector
    rot   Rotation matrix (direction cosines)

 Return:

 Calculate the plane rotation and translation by doing a fit of
 the plane equation to the surveyed points.  At least 4 points
 must be passed in the @a points array with corresponding errors
 in the array @a errors.  The arrays are assumed to contain
 TVector3 objects.

 Parameters:
    points Array surveyed positions
    errors Array of errors corresponding to @a points
    depth  Survey targets depth (perpendicular to the plane)
    trans  On return, translation of the plane
    rot    On return, rotation (direction cosines) of the plane

 Return:
    @c true on success, @c false otherwise

 Create a delta transform from a global rotation matrix and
 translation.

 Parameters:
    path   Path of element to transform.
    rot    Rotation matrix (direction cosines)
    trans  Translation
    delta  On return, the delta transform

 Return:
    Newly

 Create a delta transform from a global rotation matrix and
 translation.

 Parameters:
    global Global matrix of element to transform.
    rot    Rotation matrix (direction cosines)
    trans  Translation
    delta  On return, the delta transform

 Return:
    Newly

 Get the FMD1 plane from the survey points

 Parameters:
    rot    Rotation matrix (direction cosines)
    trans  Translation

 Return:
    @c true on success, @c false otherwise.

 Do the FMD1 analysis.  We have 4 survey targets on V0-A on the
 C-side.  These are

  - V0A_ICT  In-side, C-side, top.
  - V0A_ICB  In-side, C-side, bottom.
  - V0A_OCT  Out-side, C-side, top.
  - V0A_OCB	 Out-side, C-side, bottom.

 These 4 survey targets sit 3.3mm over the V0-A C-side surface, or
 3.3mm over the back surface of FMD1.

 Since these are really sitting on a plane, we can use the method
 proposed by the CORE offline.

 Return:
    @c true on success, @c false otherwise.

 Get the surveyed plane corresponding to the backside of FMD2.
 The plane is done as a best fit of the plane equation to at least
 4 of the available survey points.

 Parameters:
    rot    Rotation matrix (direction cosines)
    trans  Translation vector.

 Return:
    @c true on success, @c false otherwise

 Do the FMD2 calculations.  We have 6 survey points of which only
 5 are normally surveyed.  These are all sittings

  - FMD2_ITOP   - In-side, top
  - FMD2_IBOTM  - In-side, middle bottom
  - FMD2_IBOT   - In-side, bottom
  - FMD2_OTOP   - Out-side, top
  - FMD2_OBOTM  - Out-side, middle bottom
  - FMD2_OBOT   - Out-side, bottom

 The nominal coordinates of these retro-fitted survey stickers
 isn't known.  Also, these stickers are put on a thin (0.3mm
 thick) carbon cover which flexes quite easily.  This means, that
 to rotations and xy-translation obtained from the survey data
 cannot be used, and left is only the z-translation.

 Further more, since FMD2 to is attached to the ITS SPD thermal
 screen, it is questionable if the FMD2 survey will ever be used.

 Return:
    @c true on success, @c false otherwise.

 Run the task.
