Fig. 2. A-array map of the immediate neighbourhood of S68-2 (contours). Contour levels are 3, 6, 10, 15, 20 and 30 times the RMS background (5Jy). The position of the X-ray source Ser-X3 is marked by the cross. The cross is 10" from one side to the other, representing the quoted positional error of P98. The positions of infrared sources from Eiroa & Casali (1992) are also shown as circles whose diameters are 2".
