<section class="docs-section"><h2>1. Build the layer stack</h2><p>Open <strong>Plane mirrors → New plane mirror</strong>. Give the mirror a name and choose the stack type: bare substrate, single layer, custom layers, or periodic multilayer. Enter materials, thicknesses, and roughness where the form asks for them. Check the <strong>Layer stack preview</strong> beside the form, then choose <strong>Create mirror</strong>.</p><figure class="docs-shot"><img src="{{ url_for('static', filename='web-docs/plane-mirror-form.png') }}" alt="New plane mirror form showing save controls and a layer stack preview" loading="lazy"><figcaption>Mirror definition and layer stack preview before saving.</figcaption></figure><p>Find the stack later under <strong>Plane mirrors → Manage plane mirrors</strong>. Use <strong>Edit mirror</strong> on its page to change the saved stack.</p></section>
<section class="docs-section"><h2>2. Choose a reflectivity scan</h2><p>On the saved mirror page, choose <strong>Energy sweep</strong>, <strong>Angle sweep</strong>, or <strong>Monochromator</strong> under <strong>Run sweep</strong>. Enter the scan range and polarization. The <strong>Reflectivity preview</strong> responds to your settings before you select <strong>Start run</strong>.</p><p>Use <strong>Save current scan settings as a preset</strong> when you expect to repeat a setup. Independent ranges and coupled values let you compare layer or scan parameters in one run.</p></section>
<section class="docs-section"><h2>3. Review the run</h2><p>Use <strong>Plane mirrors → Manage plane-mirror runs</strong> to reopen saved results. In <strong>Plots → New plot</strong>, choose a mirror run to compare its reflectivity with other saved runs. The saved plot's <strong>Download</strong> menu offers its image and the x/y values of the displayed curves.</p></section>
