*Notes:*
   * For the Pixel status: 3-Layers Pixel (80 M channels) - 97.5%; IBL (12 M channels) - 99.3%
   * For Tilecal  the number of cells (including gap and crack counters) are included
   * For RPC, most inactive channels are due to HV channels that cannot be turned on because one (of several) gas gaps connected to that channel cannot be operated. Some of the disconnected channels    are actually operable and can be made to work by an intervention in the cavern.
   * The number of channels for AFP has doubled since last year after the installation of the second arm
   * Detectors with fewer than 100 channels are not reported

   * For Tilecal  the number of cells (including gap and crack counters) are included
   * For CSC, the number of alive channel is lower than before due to the failure of the cooling of one chamber that cannot be operated and the presence of one layer with a broken wire in another chamber
   * For RPC, most inactive channels are due to HV channels that cannot be turned on because one (of several) gas gaps connected to that channel cannot be operated. Some of the disconnected channels    are actually operable and can be made to work by an intervention in the cavern during TS1.
