(output snipped)...</pre><p>Since the second argument to the <i>getdata</i> function was set to <i>False</i>, the data array in this dictionary is an ordinary NumPy array (not a masked array). This was done so that we could manipulate the undefined values directly. The <i>metastr</i> function produces a nicely-formatted string describing the metadata in the dictionary, which when printed to the console provides an easy way to see what is provided in the dictionary without seeing the (large) data array.</p>
