Demonstrations:  Here are a few examples demonstrating the technical performance of LWA1.  Also check out science results.

Sensitivity (SEFD) determined from drift scans:

Simultaneous multifrequency drift scans of Cyg A (shown in separate plots for clarity):

Beam pointing and tracking:  Note these results are beam outputs cross-correlated against our outrigger antenna, which suppresses the Galactic background and allows one to clearly see sidelobe structure.

Characterization of main lobe and sidelobes:  Note these results are beam outputs cross-correlated against our outrigger antenna, which suppresses the Galactic background and allows one to clearly see sidelobe structure.

Confirmation of Galactic noise domination using single-dipole drift scans.  Also shows that we understand our single dipole “standalone” pattern pretty well; note we can tell which way the dipole is oriented from the drift scan. (The embedded pattern?  That’s another story…)
