class AliFMDESDFixer: public TObject

 Add a dead region spanning from FMD<d><r>[<s1>,<t1>] to
 FMD<d><r>[<s2>,<t2>] (both inclusive)

 Correct for zero's being flagged as invalid

   * Get name of object
   *
   * @return Always the same

   * @{
   * @name Noise suppression fix


   * Set the factor assumed to be used in the reconstruction.  If this
   * is set way high (>=4) then this corrector will effectively be
   * disabled.
   *
   * @param f

   * Get the factor assumed in reconstruction pass
   *
   * @return factor assumed in reconstruction pass

   * Check if we're using the noise correction.
   *
   * @return true if fRecoFactor < 4

   * Find the target noise factor
   *
   * @param esd   ESD object.
   * @param check If true, also check for correction object
   *
   * @return Needed noise factor, or 0 or less if no correction is needed
