PV Targets

Following the successful commissioning of spacecraft and payload, XRISM will undergo a 6-months Performance Verification (PV) Phase. 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.

Data of the PV phase observations are reserved to the members of the XRISM Science Team, as well as to a small number 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.

Note:

Category name: GC stands for Galactic Compact, GD for Galactic Diffuse, EGC for Extra-Galactic Compact, and EGD for Extra-Galactic Diffuse.

Coordinates values are rounded to the third decimal place. Target position may be slightly changed at each observation

Depending on the Resolve Gate Valve situation, the required exposure time is separately indicated for the Open Gate Valve (GVO) and the Closed Gate Valve (GVC).

Priority “A” targets will be given the highest scheduling priority. “C” priority targets that are not observed by the end of the PV phase will not be automatically done later in the mission.

In addition to the PV targets listed above, we may observe a black hole X-ray binary during the PV phase, using Director's Discretionary Time (DDT). Potential targets: 4U 1630-472, GRO J1655-40, H 1743-322, IGR J17091-3624, MAXI J1305-704, or other newly discovered BHXBs.
