Automated Source Finding - Duchamp
Here are some initial results of automated source finding with the GALFACTS dataset. The Duchamp source finding software has been run on the GALFACTS C-field 13 Jul 2010 Release. I have completed some preliminary source finding in the C-field 13 Jul 2010 Release with Duchamp. This is for a media...Tags: galfacts, cfield, igalfa, sources, source finding

Comment on "MIGHTEE expression of interest."
I'm still very interested in using the MIGHTEEpol data to understand the polarisation properties of faint radio sources further and their potential use in weak lensing analyses. I can potentially commit a PhD student to work on this over the next couple of years.955 days ago
