The new frames are automatically reduced using the same settings as the frames that are already in the project. It is particularly useful in an observation of short-period variables. Using this tool, it is possible to monitor the variable behavior during the observation and eventually decide, by checking a light curve, whether to resume or stop it.</p><p>During the first run, process the CCD frames by the standard procedure up to the selection of stars and produce a light curve. After acquiring a set of new frames, click on the <tt>Tools</tt> -> <tt>Process new files</tt> item in the main menu. A new dialog window appears. Select the option <tt>process new files in the directory</tt> and in the <tt>Directory</tt> field, select the directory which the new files are stored in. You can also setup file filtering conditions using the fields in the bottom part of the dialog. Only files that meet those conditions will be merged into the project. Confirm the dialog by the <tt>OK</tt> button. First, the program automatically looks up the new files in the specified location, appends them to the table of input files and performs the necessary conversion, corrections, photometry, matching. Finally the actualized light curve is built. Using the same steps, you can continue up to the end of observation.</p></body></html>
