Offsets between IMFIT’s RA_fw and Dec_fw and BLOBCAT’s RA_wc and Dec_wc. The dashed black line shows where RA_fw − RA_wc = 0 and Dec_fw − Dec_wc = 0 to help guidethe eye. The inset plot shows the histogram of the RA_fw − RA_wc and Dec_fw − Dec_wc values. The median RA and Dec offsets were − 0.002 and 0.022 arcsec and their corresponding standard deviations were 0.668 and 0.689 arcsec, respectively.
