Below are hexagonal mosaic patterns for 7, 19, 37, 61, 91, and 127 pointings. The horizontal separation is half the full-width at half-maximum beamwidth (FWHM); for CARMA the 10-m antenna FWHM should be used to ensure proper coverage. The vertical separation is sqrt(3)/2 times the horizontal separation. This hexagonal pattern gives Nyquist sampling across the map. The red cross-hatched region indicates the area over which the map will have gain equal to 1 and roughly uniform sensitivity (given by the RMS calculator). Over this area, the integration time will be about 3.5/N times lower than for a single pointing, where N is the number of pointings. Click on any image to see it full size.
