Detection or upper limits on the faint afterglow from GRBs or other sources at cosmological distances are important means of constraining the source modeling.\n  Using the Sardinia Radio Telescope (SRT), we compare the sensitivity and robustness of three methods applied to the detection of faint radio sources from raster maps around a known source position: the smart quick-look method, the source extraction method (typical of high-energy astronomy), and the fit with a 2-D Gaussian.
