ScW A * 43 (DETSIG=18.0, OFFangle=2.34) RA= 251.146 DEC= -21.627 B 72 (DETSIG=24.9, OFFangle=2.69) RA= 251.837 DEC= -21.505 C 72 (DETSIG=18.1, OFFangle=0.51) RA= 249.479 DEC= -20.214 D * 81 (DETSIG=19.6, OFFangle=2.63) RA= 253.280 DEC= -13.593 E 82 (DETSIG=19.5, OFFangle=2.63) RA= 246.859 DEC= -17.715 Apart perhaps for the last source (E) these sources unfortunately turn out to just be artefacts or ghosts (at least sources A and D are exactly 8.3 degrees) from Sco X-1. It seems to me that the images from pointings 43, 72, and 81 look like the mask of JEM-X2 is shadowing from Sco X-1. Could someone confirm this is the case?
