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.
IXPE Archive Access
IXPE data can be accessed through the following HEASARC multi-mission interfaces:
The IXPE Caldb has been updated for the XRT (version 20221021) and the GPD (version 20221020). Downloads are available from the IXPE Calibration page. Users can also access the HEASARC caldb remotely.
