RXJ1856.5-3754 Isolated Neutron Star Observations
2001-11-09
The five observations totalling 500 ks on the isolated neutron star RXJ1856.5-3754 have been released. Data products have been collected into five separate tar files, one for each ObsId; included are all primary and secondary data products except for the Level 1 and Level 1.5 Event files. Additional products may be retrieved through ChaSeR. In addition, we provide files containing the combined spectra and the exposure weighted ARF files for the four most recent observations, as well as all five observations.
More information on the processing and analysis of these data may be found at the official release page.
These are the pre-packaged files available for download:
