The supernova remnant (SNR) Puppis A, a source that includes the central compact object RXJ0822-4300, relics of the precursor star and traces of the interaction between the SN shock and the dense surrounding gas, has been extensively studied from radio to GeV gamma-rays. However, the existing X-ray images surprisingly lack a considerable portion of the source towards the south and southwest.We report the first detailed full view of Puppis A in X-rays (with images in the 0.3-0.7, 0.7- 1.0 and 1.0-8.0 keV bands) based on the combination of new XMM-Newton observations with existing XMM-Newton and Chandra data. From these images we investigate in detail the SNR morphology, carry out multiwavelength comparisons and estimate the flux density and luminosity of the whole SNR. We have also collected and updated the broad-band data of Puppis A across the whole electromagnetic spectrum, producing the Spectral Energy Distribution (SED) and reanalyzed radio data to estimate the minimum energy stored in relativistic particles, as well as the magnetic field strength, useful parameters to set constraints on the mechanisms that give origin to the high-energy emission.
