Category Description

     Data items in the ARRAY_DATA category are the containers for
     the array data items described in the category ARRAY_STRUCTURE.
    
     It is recognized that the data in this category needs to be used in
     two distinct ways.  During a data collection the lack of ancillary
     data and timing constraints in processing data may dictate the
     need to make a 'miniCBF' nothing more than an essential minimum
     of information to record the results of the data collection.  In that
     case it is proper to use the ARRAY_DATA category as a
     container for just a single image and a compacted, beam-line
     dependent list of data collection parameter values.  In such
     a case, only the tags '_array_data.header_convention',
     '_array_data.header_contents' and '_array_data.data' need be
     populated.
    
     For full processing and archiving, most of the tags in this
     dictionary will need to be populated.
