Following the successfull commissioning of spacecraft and payload, XRISM will undergo a 6-months Performance Verification Phase (PVP). The goal of this phase is to showcase the XRISM transformational science, while providing the scientific community worldwide with a comprehensive set of experiments thoroughly verifying the capability of the mission to fulfill all its scientific goals.

The list of PVP targets approved by the XRISM Science Management Office Steering is shown below. Note that:

  • The first column indicates the Category Team ​​​​​​​to which each Target belongs: GC=Galactic Compact; GD=Galactic Diffuse; ECG=Extra-Galactic Compact; EGD=Extra-Galactic Diffuse
  • Priority A observations will be either observed during the PVP, or carried to later phases of the mission if a successfull observation during the nominal PVP is not possible
  • Priority C observations will be used to optimise the observational efficiency during the PVP, and have a probably of about 50% to be actually observed. Priority C observations not performed during the nominal PVP will not be carried to later phases of the mission
  • 5% of the PVP observing time will be reserved to calibration observations (the corresponding target list will be published shortly)
  • 8% of the PVP observing time is allocated to "observatory time" including Director's Discretionary Time (to be used, for instance, for low-probablity Target-of-Opportunity events)
  • Data of the PVP observations are reserved to the members of the XRISM Science Team, as well as to a small numer of "XRISM Guest Scientists" to be appointed by the XRISM Participating Agencies by the end of 2021. Data will be made public following the rules holding for all XRISM proprietary data
  • A small set of Early Release Science data will be made public at the time of the first Guest Observer opportunity
  • The boresight coordinates of each PVP observation will be announced soon.

 For any questions on the XRISM PVP, you are welcome to contact the XRISM ESA Project Scientist.
