An overview of the beamformed file structure, encapsulated in a hierarchical tree within an HDF5 file. The data are split into separated sub-array pointing (known in this paper as station beams); within each sub-array pointing are pencil or tied-array Beams (we will use tied-array beams), along with coordinates and processing information; each Beam contains a data structure with either 4 Stokes  parameters (or just Stokes I for total intensity) or, if desired, the amplitude and phase of the X and Y polarisations separately. Header keywords are stored within each tree level, depending on their hierarchical relevance to the rest of the file, as the information is inherited as one steps downward through the tree structure. See Alexov et al. (2010a,b) for more details.
