Fig. 1


Digital-Sky-Survey II red image of the North-America and Pelican nebulae (inverted grayscale), with overlaid the regions covered by XMM-Newton observations (big circles), and Chandra ACIS observations (squares), each labeled with its ObsId number. X-ray fields of view are drawn in red for new data, and black for archive data. ACIS-I ObsIds 13467 and 15592 share the same pointing direction and roll angle. Archive XMM ObsIds 0656780701 and 0656781201 also share the same pointing direction, but with a slightly different roll angle; only 0656780701 is labeled in the figure. Small green squares are the H58 emission-line stars; blue crosses are YSOs from RGS11. Yellow circles indicate positions and approximate sizes of the Cambrésy et al. (2002) clusters of 2MASS NIR sources. The three bigger star symbols indicate respectively the O5 star 2MASS J20555125+4352246 (cyan), the FU Ori object candidate HBC722 (=V2493 Cyg = 2MASS J20581702+4353433, green), and the FU Ori star V1057 Cyg (=2MASS J20585371+4415283, orange).
