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,
Note: these beam maps are not nyquist sampled over
the entire 2d range. They are the output of the model.
The beams are contoured in 3 db steps.
The Beam maps:
