<p>Note that the topography B = eta - h, so it is not necessary to store all
three of these. Also, B is often the same for all frames, so rather than
storing B at each frame as a qoi, two other options are also provided
(and then storing eta or h for all frames allows calculating the other):</p>
<p>include_Bfinal: If True, include the topography B array from the final frame
as the Bfinal array.</p>
<p>include_B0: If True, include the topography B array from the first frame
as the B0 array. This is only useful if, e.g., the first frame is initial
topography before co-seismic deformation, and at later times the topography
is always equal to Bfinal.</p>
<p><cite>description</cite> is a string that will be added as metadata.
A metadata field <cite>history</cite> will also be added, which includes the
time the file was created and the path to the directory where it was made.</p>
