Descripción
The Very Small Array (VSA) is a synthesis telescope designed to image
faint structures in the cosmic microwave background on degree and
sub-degree angular scales. The VSA has key differences from other CMB
interferometers with the result that different systematic errors are
expected. We have tested the operation of the VSA with a variety of
blank-field and calibrator observations, and cross-checked its
calibration scale against independent measurements. We find that
systematic effects can be suppressed below the thermal noise level in
long observations; the overall calibration accuracy of the flux density
scale is 3.5 per cent and is limited by the external absolute
calibration scale.
