Fig. 5
Surface-brightness radial profiles of the source T Pyx extracted from a sector-area of opening angle 30 degrees. From left to right: radial profiles are in the eastern, western, northern, and southern directions. A Chandra ACIS-S3 PSF radial profile of about 250−300 photons calculated from the same sector is overplotted for comparison with Fig. 4. Gaussian errors are assumed.
