Notes:

  • RMS noise is listed for XX polarisation only (σXX). For Stokes I, σI=√ (σXX2+σYY2)/2=σXX/√ 2(for unpolarised sources) when I is defined as I=(XX+YY)/2 (as is typical for synthesis arrays). Alternatively, σI=√ (σXX2+σYY2)=√ 2·σXX(for unpolarised sources) when I is defined as I=XX+YY (as is often used for single-dish).
  • Colour bar is in units of Jy/beam.
  • Positive and negative peak of the PSF are shown with green and red crosses respectively.
  • Fitted beam is shown with a green ellipse.
  • A file containing all of the available PSF characteristics is available in

    comma-separated (CSV) format.
