        <para>
            The BaseOps application is part of a suite of computer programs
            --- the Noisemap suite --- that is used to calculate the noise
            impacts from aircraft operations near an airbase. BaseOps allows
            you to enter a description of aircraft operations --- the aircraft
            used, the flight profiles flown, the number of daily operations,
            etc.
        </para>
        <para>
            Once the aircraft operations data has been entered into BaseOps,
            the case must be run. Running a case refers to executing the computer
            programs that actually perform the numerical computations necessary
            to predict the noise levels.
        </para>
        <para>
            After the case has been run, the predicted noise levels can be
            view in a variety of ways, including noise contour maps and point-of-interest
            reports.

            This lesson will teach you how to run a BaseOps case. It is presented
            as a list of step-by-step instructions. To begin, press the <bold>First

        <para>
            BaseOps has a number of options that affect how a case is run.
            Before running the case, you should verify that these options
            are correctly set.
        </para>
        <para>
            Go to the object type selector dropdown list in the upper-left
            corner of the BaseOps window, and select "Run". The controls for
            editing the run options will be displayed in the lower-right portion
            of the BaseOps window.

        <para>
            There are several mathematical methods for calculating
            a number representing the impact of noise at a location. These
            are referred to as <italic>noise metrics</italic>. A commonly-used
            example is the Day-Night Average Sound Level (DNL).
        </para>
        <para>
            Use the dropdown list labeled "Noise metric" to select the metric
            that will be calculated when the case is run. You have the following
            five choices.

            <para>
                DNL (or, in California, CNEL) is the most common noise metric
                used. If someone requests noise contours, it is likely they are
                looking for DNL/CNEL contours.

            The "Compute grid" and "Compute points of interest" checkboxes
            are used to control which parts of the noise analysis are performed.
            Typically, you will want to make sure both of these boxes are
            checked.

        <para>
            BaseOps allows you to define different scenarios. A scenario is
            a set of case modifications, such as scaling flight profile operations.
            Scenarios are covered by another lesson in this tutorial series.
        </para>
        <para>
            BaseOps allows you to select which scenario(s) you wish to run.
            However, you will typically want to run all of them. Insure that
            "Run All Scenarios" is selected in the dropdown list.

        <para>
            Running a case consists of performing a number of steps. BaseOps
            allows you to select a subset of these steps to perform when you
            run the case. However, you will typically want to perform all
            of the steps. Insure that "Perform All Steps" is selected in the
            dropdown list.

        <para>
            Before running the case, BaseOps performs a check on the case's
            data. It is possible that errors will be found. If so, an error
            report will be displayed in the lower-right portion of the BaseOps
            window.

        <para>
            Each error should have one or more links that will take you to
            the locations in BaseOps where the error can be corrected. Click
            on these links, correct the error, then run the case again.

        <para>
            If the case runs successfully, a report, stating that no errors
            occurred, will be displayed in the lower-right portion of the
            BaseOps window.

            You can now view the results of the run: view noise contours using
            NMPlot, view the point-of-interest report, etc. This is covered
            in later lessons in this tutorial series.
