<p>The dialog can be activated:</p>
<ol class="arabic simple">
<li>from the main menu: <em class="menuselection">Tools ‣ Open file</em>.</li>
</ol>
<p>When a file is opened, the program checks its content and decides which kind of

<p>(1) The chart is displayed in the preview area. It is possible to switch between
several rendering modes.</p>
<p>(2) When you place a cursor over an object, the position and brightness (if available)
is displayed in the status bar.</p>
<p>(3) You can zoom the preview in and out by means of the zoom icons on the toolbar.
The actual magnification is shown here.</p>
<p>(4) You can change the aperture for which brightness of objects are rendered.</p>
<p>(5) The local menu bar provides following functions:</p>
<ul>
<li><p class="first">Menu File:</p>

<li>Show properties - display the further details about the file. Full header preview

<h2>Object inspector tool<a class="headerlink" href="#object-inspector-tool" title="Permalink to this headline">¶</a></h2>
<p>The Object inspector tool is a tool which displays that the program registers about
an object on a frame. The main purpose of this tool is for testing and debugging. Unlike the
Quick Photometry, the Object Inspector shows results, that has been obtained during the “full”
photometry. Because of this, calibration and photometry must be performed first. The results
are more relevant.</p>
<p>To activate the tool:</p>
<ol class="arabic simple">
<li>From the local menu, select <em class="menuselection">View ‣ Chart only</em>
or <em class="guilabel">Image and chart</em> to show the objects.</li>
<li>From the local menu, select <em class="menuselection">Tools ‣ Object inspector</em>.
A new panel on the right side of the preview window appears.</li>
</ol>
<div class="figure align-center">
<img alt="Object Inspector tool" src="_images/phtfile_couts2.png" />
<p class="caption">Object Inspector tool</p>
</div>
<p>Using the left mouse button, click on the image (1), to select an object. The object is
highlighted and its properties are displayed in the right panel (2).</p>
<p>The following object parameters are presented:</p>
<ul class="simple">
<li>Object # - object’s ordinal number on the current frame.</li>
<li>Reference ID - object’s ordinal number on a reference frame.</li>
<li>Center - coordinates of the object’s centroid</li>
<li>Brightness - instrumental brightness of the object in magnitudes.</li>
<li>Error - error estimation of brightness in magnitudes.</li>
</ul>
<p>Several dimensions are presented in the image area (3):</p>
<ul class="simple">
<li>Two blue circles show the annulus which is used to estimate the background properties.</li>
<li>A green circle shows the size of the aperture.</li>
</ul>
<p>(4) Here, you can change the current aperture.</p>
