It works on all modern operating systems, but not on mobile devices.\n </li>\n <li>Kotlin-Js application to run in the browser. It works in any browser. This version is currently under development.\n </li>\n </ul>\n <h3 id=\"приложение\">Application</h3>\n <p>To start, you must have the installed platform JVM 8.</p>\n <h4 id=\"установка-jre\" style=\"margin-bottom: 0px\">Установка JRE</h4>\n <p>This program requires <a href=\"https://en.wikipedia.org/wiki/Java_virtual_machine\">Java Runtime Environment </a> version 8 (it will probably work on 7, but it has not been tested. JRE is installed by default on the vast majority of personal computers. You can verify the installed version with the command <code> java -version </code>. If platform is not installed, or an old version is installed, then you need to install it. </p>\n <ul>\n <li><strong>Windows:</strong> Go <a\n href=\"http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html\">here</a>,\n download and install.\n </li>\n <li><strong>Ubuntu / Debian:</strong> Instruction available <a\n href=\"https://www.digitalocean.com/community/tutorials/how-to-install-java-on-ubuntu-with-apt-get\">here</a>.\n </li>\n <li><strong>Red hat / CentOS:</strong> Instruction available <a\n href=\"https://www.digitalocean.com/community/tutorials/how-to-install-java-on-centos-and-fedora\">here</a>.\n </li>\n </ul>\n <p>If you use OpenJDK, then an additionally <code>openjfx</code> package must be installed. On systems that use <code>apt-get</code>, this is dony with <code>sudo apt-get insta openjfx</code>.</p>\n <h4 id=\"запуск\">Launch</h4>\n <p>\n After that, just download the archive with the program <a\n href=\"http://npm.mipt.ru/confluence/pages/viewpage.action?pageId=10027425\">from here</a> unzip the program to any directory and run the executable file from the <code>bin</code> directory (batch-file for Windows or shell-script for Linux).\n </p>\n <h3 id=\"web-версия\">Web-version</h3>\n <p>\n The test version of the web-version of the program is available at <a href=\"../apps/biref\">http://npm.mipt.ru/apps/biref</a>.\n The web version works in exactly the same way as the Java version. To run it, you do not need to install anything, just follow the link. It is currently in test mode.\n </p>\n</div>\n<h1>Additional theoretical background</h1>\n<p>Additional materials on the mathematical and physical substantiation of the work of analysis programs can be found <a href=\"/files/biref.pdf\">here</a>.</p>\n<h1>Additional task</h1>\n<h2>1. Data entry</h2>\n<p>For further work, you must enter data in the table. This can be done manually or by loading text data from a file.</p>\n<h2>2. Checking the error</h2>\n<p>In the work, there are practically no parameters that can have a significant systematic bias, and the main error comes from the inaccuracy of measuring angles. Moreover, the value of this error is set from naive considerations, since the measuring dial in this case does not have any particular accuracy class.</p>\n<p>You can verify the accuracy of the error determination according to the graph of the refractive index of an ordinary wave. From theoretical considerations, it is known that the points of this graph should lie on a straight line with zero slope (constant). The scatter of points relative to this line should be purely statistical in nature. If the error values are signific
