Left panel: Chandra image of G306.3−0.9 in three X-ray energy bands: soft (0.5−1.0 keV) in red, medium (1.0−2.0 keV) in green, and hard (2.0−4.5 keV) in blue. Soft X-ray point-like sources at the geometrical center of the SNR (2, , J2000.0) and in the northeast part of the source are indicated as “PS C” and “PS N”, respectively. A hard point-like source is indicated in the southern region as “PS S”. Right panel: combined XMM-Newton PN, MOS1, and MOS2 image in the same energy ranges. Point-like sources are also indicated with individual yellow circles.
