Series expansions for computing rhumb areas

<p>This data accompanies the paper</p> <blockquote>C. F. F. Karney,<br> <a href="https://arxiv.org/abs/2303.03219">The area of rhumb polygons</a>,<br> Technical Report, SRI International, March 2023.<br> <a href="https://arxiv.org/abs/2303.03219">https://arxiv.org/abs/2303.03219</a></blockquote> <p>Files:</p> <ul> <li><code>rhumbarea.mac</code>: the Maxima code used to obtain the series expansion for the rhumb area. Instructions for using this code are included in the file.</li> <li><code>auxvals40.mac</code>: the 40th-order series for auxiliary latitudes as Maxima code (required by rbumbarea.mac).</li> <li><code>rhumbvals40.mac</code>: the 40th-order series for the rhumb area as Maxima code.</li> <li><code>rhumbvals6.m</code>, <code>rhumbvals16.m</code>, and <code>rhumbvals40.m</code>: the 6th-, 16th-, and 40th-order series as Octave/MATLAB code. The 40th-order series are given as floating-point numbers; the others are as exact fractions.</li> </ul>
