Dirty beam inconsistent with the INVERT FWHM parameter?
Posted: Mon Jun 22, 2020 8:22 am
Hi,
I wish to plot a pulsar wind nebula and measure its flux density.
During my process of “INVERT”, I set the uv tapering with a FWHM 20”x20”; however, the FWHM of the dirty beam model is around 15”x15”.
May I inquire why the dirty beam size is inconsistent with the Fwhm set during “INVERT ”, and how should I select the beam size of the cleaned image during the process of “RESTOR”,if I want to measure the flux density?
Many thanks in advance.
