    // Conditions data are normally organized by feb, identified by
    // the febid. Each feb then has 128 channels of conditions data.
    // In addition, there are corrections stored one per channel with
    // their channel id.
    //
    // In certain cases, not all 128 channels will have conditions
    // data. For normal conditions, space data may arise from channels
    // that could not be treated, or other failures. For MC
    // conditions, this data may be sparse due to the use of implied
    // symmetry of the detector and so only a subset of febs and a
    // subset of their channels are present.
    //
    // For the 'normal' dense set of conditions, it is sufficient to
    // save the set of febids since the number of channels is known.
    //
    // For sparse conditions, we save both the febid and a bit map
    // indicating which channels contain data.
    //
    // For corrections, we save separately the channel ids.
