IXPE Data ArchiveThe 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 AccessIXPE data can be accessed through the following HEASARC multi-mission interfaces:
Latest NewsThe IXPE Quick Start guide has been updated to include the use of the ixpecalcarf tool to generate observation specific response files. The IXPE Caldb has been updated for the XRT (version 20231201) and the GPD (version 20240125). Please see the release notes for details. Downloads are available from the IXPE Calibration page. Users can also access the HEASARC IXPE caldb via remote access. The Sun angle constraint has been updated in the Viewing tool for the IXPE mission. The IXPE Caldb has been updated for the XRT (version 20230526) and the GPD (version 20230526). Please see the 20230526 release notes for details. Downloads are available from the IXPE Calibration page. Users can also access the HEASARC IXPE caldb via remote access. IXPE made the cover of the May 2023 edition of Nature Astronomy with a polarized view of the Crab. The work by Bucciantini et al. provides insight into the magnetic field morphology and the generation of turbulence in this young supernova remnant system. |
