Lbw Beam maps



    The calibration scans (see ao technical memo 2000-04) does two crosses (each leg  6 beam widths long) about a source. The crosses are rotated by 45 degrees from each other. The analysis then fits a model to the main beam and the first sidelobe. This model is used below to create beam maps at various azimuths,  zenith angles, and frequencies.
    Note: these beam maps are not nyquist sampled over the entire 2d range. They are the output of the model.

The Beam maps:

    The beams are contoured in 3 db steps.
