Column (1): Apertif source name; Cols. 2 and 4: RA and Dec; Cols. 3 and 5: RA and Dec errors; Cols. 6 and 8: Total and peak flux density; Cols. 7 and 9: Integrated and peak flux density uncertainties;
and Cols. 10, 12, and 14: Deconvolved major and minor source size and position angle. A source size value 0.0 means that the PSF cannot be deconvolved from the fitted source along the given axis, and the corresponding uncertainty represents an upper size-limit estimate. The position angle is given in degrees ranging from --90 to 90 deg west to east through north. When both major and minor sizes are given as 0.0, the position angle is omitted. Columns 11, 13, and 15: Uncertainties of the major and minor source size and position angle; Col. (16): Local background noise rms; and Col. (17): Source type as classified by PyBDSF, with 'S' as an isolated source fitted with a single Gaussian; 'C' as sources that were fit by a single Gaussian, but are within an island of emission that also contains other sources, and 'M' as sources fit with multiple Gaussians.
