The Fundamental Performance of FAST with 19-beam Receiver at L Band

Understand

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) passed national acceptance and is taking pilot cycle of 'Shared-Risk' observations.

• The 19-beam receiver covering 1.05-1.45 GHz was used for most of these observations.
• The electronics gain fluctuation of the system is better than 1\% over 3.5 hours, enabling enough stability for observations.
• Pointing accuracy, aperture efficiency and system temperature are three key parameters of FAST.
