Fig. 21


The upper row of figures shows the observationally determined station beam patterns as described in the text. On the left, the beam is shown for core station CS004 in its LBA_INNER configuration. On the right, the beam is shown for a single HBA ear of the same core station. The peak response is normalized to unity in both plots. Note the low-level sidelobe structure apparent in the figures. The bottom row of plots gives the FWHM for a Gaussian fit to the main station beam lobe, plotted as a function of frequency. Solid lines indicate the fitted αλ/D relations explained in the text.
