<h1>Features</h1>
<ul>
<li>Munipack is a free open source tool which aim is to be
a software eye of an astronomer.</li>
<li>Munipack's goal is to implement easy-to-use tools for all
astronomical astrometry and photometry, access to
Virtual observatory as well as FITS files operations
and even more.</li>
<li>Munipack provides a <a href="basic.html">simple user interface</a>
along with a powerful processing engine.</li>
</ul>
<h2>General</h2>
<ul>
<li>All results are estimated by
<a href="http://en.wikipedia.org/wiki/Robust_statistics">robust statistical</a>
methods. Mixed statistical distributions or random outliers does not matter
in this robust approach.</li>
<li>As the heart of optimisation methods, <a href="http://en.wikipedia.org/wiki/MINPACK">Minpack</a> has been selected (<a href="http://www.netlib.org/minpack/">source code by Netlib</a>).
</li>
</ul>
<h2>Astrometry</h2>
<p>
Munipack has implemented the very complex
<a href="man_astrometry.html">astrometry</a> module:
</p>
<ul>
<li>Robust statistical estimators and algorithms are implemented.</li>
<li>Mutual correspondence of an astrometric catalogue and processed images
is determined by a developed matching algorithm on base of back-tracking.</li>
<li>As the star position source, a catalogue or an already calibrated image can be
provided.</li>
<li>Astrometry calibration can be stored in <a href="dataform_astrometry.html">FITS
header</a>.</li>
</ul>
<h2>Photometry</h2>
<p>
Munipack provides the classical method detection of stars
and the aperture photometry on base of DAOPHOT II.
</p>
<ul>
<li>Automatic <a href="man_find.html">detection</a> of stars</li>
<li><a href="man_aphot.html">Aperture photometry</a> of stars</li>
<li><a href="grow.html">Growth curve photometry</a> of stars</li>
<li><a href="phoverview.html">A novel approach</a> on photometric calibration
has been developed.</li>
<li>The calibration on <a href="man_phcal.html">absolute fluxes</a> is possible.</li>
<li><a href="man_phfotran.html">Photometric System Transformation</a>
can be determined.</li>
</ul>
<h2>Photometric Pre-Corrections</h2>
<p>A standard way to correct for all the <a href="man_bias.html">bias</a>,
<a href="man_dark.html">dark</a> and <a href="man_flat.html">flat-field</a>
frames is implemented.
</p>
<ul>
<li>Averaging is implemented by robust statistical methods (eg. suppress
defects like cosmic-ray events)</li>
<li>Flat-fielding can be applied on series of twilight frames, including different
levels of illumination.</li>
</ul>
<h2>Data Products</h2>
<ul>
<li><a href="man_timeseries.html">Time-series (light curves)</a></li>
<li><a href="man_kombine.html">Deep fields and mosaics</a></li>
<li><a href="colorspace.html">Universe in natural colours</a></li>
</ul>
<h2>Colour Imaging</h2>
<ul>
<li><a href="colorfits.html">Developed</a> colour FITS convention</li>
<li>Create of colour images in natural (not false!) colours from
observations in astronomical <a href="colorspace.html">Johnson BVR bands</a>.</li>
</ul>
<h2>Graphical Interface</h2>
<p>Properties of Viewer:</p>
<ul>
<li>Analysis of FITS format structure</li>
<li>Munipack is set as system default FITS images viewer.</li>
<li>Basic (astronomical) operations with frames</li>
<li><a href="itone.html">Advanced image processor</a> supporting an infinite dynamic range</li>
<li><a href="colorspace.html">Advanced colour management</a></li>
<li>The image composition in false and natural colours</li>
<li><a href="astoverview.html">Astrometric calibration of images</a></li>
</ul>
<p>Properties of browser:</p>
<ul>
<li>A fast thumb-nailing tool</li>
<li>Batch operations on large lists of files</li>
<li>Recognition of structure of usual FITS files including tables and multi-HDU extensions</li>
<li>Import of digital camera RAW photos (CR2, RAW, …) to colour FITS</li>
<li>Common photometric reductions (dark, bias corrections, flat-fielding)</li>
<li>Search of FITS headers</li>
</ul>
<h2>Software Properties</h2>
<ul>
<li>Munipack is designed as a multi-platform application.
Developed and currently maintained only under GNU/Linux.
<!--
Developed under GNU/Linux, possibly
working under Mac OS X, MS Windows and others.
Munipack is designed pretty much portable and multiplatform but every platform needs <em>a fine tunning of details which wasn't done yet.</em>
-->
</li>
<li>Munipack is developed on top of <a href="http://www.wxWidgets.org/">wxWidgets⤴</a>, a C++ toolkit.
</li>
<li>Both graphical and command-line interfaces are available.</li>
<li>All functionality can be scripted. Therefore, one is prepared for a batch
processing of large amount of the astronomical data
(for preparation of data pipelines).</li>
<li>Munipack's functional core is split onto working modules. They are designed
as independent routines written (mostly) in Fortran 95. They are
available directly and can be controlled via standard input and output
(possibly providing a network access, a scripting language wrapper, etc).</li>
