This curve is used to check the precision of a telescope mount. The offsets are relative to the reference frame, they are computed separately in X and Y direction. Activating the dialog --------------------- The dialog can be activated: #. from the main menu: :menuselection:`Make --> Track curve`. Making a track-list ------------------- .. figure:: images/tracklist_couts.png :align: center :alt: Track-list dialog Making a track-list \(1) The list of available data sets is displayed here. The actual data set is shown here. Click the "Save" button (3) to save the light curve to the file. Context menu ------------ You can select an individual point by a right click, you can also select more than one point by pressing a Shift key and left mouse button and drawing a rectangle in the graph. Then, click the right mouse button on a point in the selection to open the context menu. It provides following functions: - Show frame - it shows a preview to a selected frame. It is not allowed when more than one frame is selected. - Show properties - it opens a new dialog with properties of selected frame. It is not allowed when more than one frame is selected. - Delete from data set - selected measurements are removed from the current curve, the data will be shown again when you make a new curve or :guilabel:`Rebuild` the actual curve. - Remove from project - source frames corresponding to the selected measurements are removed permanently from the list of input files and such measurements won't be included in any other output. It is not allowed to remove a reference frame. Statistics ---------- The Statistics is a tool that computes and shows the minimum, maximum, sample mean and standard deviation. To activate the tool: #. From the local menu, select :menuselection:`Tools --> Statistics`. A new panel on the right side of the preview window appears. If no points are selected, all points in the data set are included in the computation. To restrict the data for the statistics, press and hold the Shift key and draw a rectangle in a graph while you keep the left mouse button pressed down. Measurement ----------- The `Measurement` tool displays two cursors in the graph. The cursors can be adjusted by dragging them using the left mouse button. The position of each cursor, their distance and statistics for the data between cursors is presented. To activate the tool: #. From the local menu, select :menuselection:`Tools --> Measurement`. A new panel on the right side of the preview window appears. .. figure:: images/measurement.png :align: center :alt: Measurement tool Measurement tool \(1) Choose the axis you want to measure. \(2) Positions of the cursor 1 and 2 are displayed here. \(3) Distance between cursor 1 and 2. \(4) When cursors are defined on the independent (X) axis, number of points (frames) between cursor 1 and 2 are displayed and also minimum, maximum, mean value and sample deviation are presented. .. seealso:: :ref:`light-curve-dialog`
