XRISM Performance Verification Data Public Release
We are pleased to announce the public release of the XRISM Performance Verification (PV) phase data. This is the first large set of XRISM observations to be made available to the worldwide astronomical community.
The PV phase for XRISM consisted of the first six months of science observations for the mission, with the goal of providing the scientific community worldwide with a comprehensive set of observations thoroughly verifying the capability of the mission to fulfill all its scientific goals. This phase lasted from February through August of 2024.
