These uncertainties result in the following uncertainty in the magnetometer azimuth as a function of azimuth:
Here are details on the shift of Ka1/2 by -0.5 degrees in azimuth (click

|beam broadening||number of samples||coverage||mean shift||shift direction|
Here is what the beam broadening looks like in the other channels.
Remember, channel pairs (e.g. Ka1/2) are identical. Also, a positive
or negative shift makes almost no difference in the map of total beam broadening.
The pictures below use a shift of -0.5 degrees in azimuth.
Finally, here are plots of the number of samples (weighted) or pixels (unweighted) above a certain threshold in beam broadening. The pixel size is 0.1 degrees, so in large pixels, the few pixels with the largest broadening would likely be suppressed. Click on the graphs for a PS version.
The beam sizes are from 0.65 to 0.9 degrees, so the beam broadening due to an azimuth shift of 0.5 degrees in either direction has a significant impact on the maps.
