IXPE Data Archive

The IXPE data are processed at MSFC after completion of a science observation and then sent to the HEASARC for archiving. After a three month checkout period, the data will be publicly available within one week of the observation completion. Note: It is still very early in the IXPE mission and flaws are being found in the processing and fixed. For each observation a readme file is being included in the archive that describe know issues with the processing for that observation.

The data products are provided as event lists of processed tracks giving polarization information in sky coordinates. This processing is described in the IXPE Observatory User Guide. Also archived are the lower level event files as well as housekeeping and auxiliary data, though these are not needed for most science use cases.

Note that some observations include data from a number of different time periods.

It is strongly recommended that publications using IXPE data include the following acknowledgement: "This work reports observations obtained with the Imaging X-ray Polarimetry Explorer (IXPE), a joint US (NASA) and Italian (ASI) mission, led by Marshall Space Flight Center (MSFC). The research uses data products provided by the IXPE Science Operations Center (MSFC), using algorithms developed by the IXPE Collaboration, and distributed by the High-Energy Astrophysics Science Archive Research Center (HEASARC)."
