True-color X-ray images of individual observations, slightly smoothed to emphasize point sources. Red: 0.4–1.2 keV; green: 1.2–2.4 keV; blue: 2.4–7.9 keV. Panel a), upper left: ACIS-I ObsId 13648 (in the Gulf of Mexico). The ACIS-I FOV size is 16.9 arcmin on a side. b), upper right: ACIS-I ObsId 13647 (“Pelican”). c), lower left: ACIS-I ObsId 15592, with same pointing as ObsId 13647 (panel b)). Comparison with this latter ObsId makes source variability very evident. d), lower right: XMM-Newton ObsId 0679580101 (“Pelican hat”). In all XMM-Newton images shown here, MOS1, 2 and PN data are combined together.
