# FITS sample: WFPC2ASSNu5780205bx.fits (HST WFPC II): Representation Information from the archive
#
# A Representation Information manifest: the Data Object(s) below, where their
# bits are, and the OAIS Representation Information needed to interpret them --
# structure descriptions (equivalent alternatives: any one will do), how to view
# the data, and what its elements mean. Every file is named explicitly; relative
# locations resolve against this file's own location.
