  • XRISM tools available for Cycle 1 GO proposals (21 Feb 2024)
    The XRISM Proposer's Observatory Guide, response files and tools for GO proposal feasibility are now available. In addition, because the Resolve aperture door ("gate valve") has not yet opened, the exposure time limit for GO proposals has been increased to 300 ks per pointing. However, the overall limit per proposal is still 600 ks.
  • Update to Enhanced Visibility Calculator (09 Feb 2024)
    The NICER enhanced visibility calculator, which provides detailed target visibility information taking into account blockages by ISS structures and other constraints, has been updated. This update allows calculation of target visibilities using orbit day target/sun angles greater than 90 degrees, appropriate for targets observed during ISS orbit day in the presence of the XTI light leak. The update also allows the user to calculate visibilities for observations restricted to orbit night or orbit day.
  • eROSITA DR1 caldb installed at the HEASARC (08 Feb 2024)
    The DR1 version of the eROSITA CALDB has been installed at the HEASARC, and the HEASARC caldb.config file has been updated to include the eROSITA CALDB data.
  • Swift UVOTA CALDB updated (08 Feb 2024)
    The Swift UVOTA caldb has been updated to version 20240201 ...
  • First eROSITA sky-survey data release (31 Jan 2024)
    Today, the German eROSITA consortium released the data for its share of the first all-sky survey by the soft X-ray imaging telescope flying aboard the Spectrum-RG (SRG) satellite. With about 900,000 distinct sources, the first eROSITA All-Sky Survey (eRASS1) has yielded the largest X-ray catalogue ever published. Along with the data, the consortium released today a series of scientific papers. See press release here.
  • NuSTAR Caldb Update (30 Jan 2024)
    The NuSTAR FPM caldb was updated to version 20240130. This release includes a new clock correction file, v176. Please see the release notes for more details.
