Description:

   Data items in the CELL category record details about the
   crystallographic cell parameters.

Examples:

Example 1 - based on PDB entry 5HVP and laboratory records for the structure corresponding to PDB entry 5HVP.

    _cell.details
    ; The cell parameters were refined every twenty frames during
      data integration. The cell lengths given are the mean of
      55 such refinements; the esds given are the root mean
      square deviations of these 55 observations from that mean.
