<h2><a name="pixfoot">B.5 <code>pixfoot</code>: Generates Multi-Order Coverage maps</a></h2>
<p><code>pixfoot</code> takes a list of sky positions from an input
table and generates a pixel map describing a sky region which includes
them all.
Currently the output is to a format known as a
<a href="http://www.ivoa.net/Documents/MOC/">Multi-Order Coverage map</a> (MOC),
which is a HEALPix-based format composed of a list of HEALPix pixels
of different sizes, which can efficiently describe complex regions.
Other output formats may be introduced in the future.
</p>
<p>See also the
<a href="uk.ac.starlink.ttools.func.Coverage.html">Coverage</a> class
for MOC-related functions.
