Early Release Data

Below are the early release (ER) data, which observers can use to get familiar with XRISM observations, especially in the context of the Cycle 1 Proposals. The data include X-ray images or spectra (in FITS format) obtained and reduced during the commissioning or calibration operations of the Resolve and Xtend instruments aboard XRISM. Note that the event files are not provided.

Another important note is that these data were extracted assuming the current, still preliminary, calibration. While the calibration is advanced enough to demonstrate the data quality, reliable scientific results cannot be derived from these data products until full data and calibration are available.
