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 need 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, beamline-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.
