<h2>Analemma</h2>
<p>
This applet shows how analemma of Sun would vary as a function of various parameters. &#955;_p stands for perihelion position shown on slider from 0 to 360 deg. starting from 1st January, &#947; is the vernal equinox position (similar slider), &#949; is inclination of the earth's axis, e is the eccentricity of earth's orbit, &#966; is latitude of the observer and H is the hour angle (time after the local noon) in hours.<br/>
<br/>
Play with the slider d to get shape of analemma.</p>
