Proposals & Tools


This material is in support of the upcoming call for Guest Scientists.

The table below contains links to software and support files, tar files as well as documentation, which allow the user to simulate events and spectra for the Resolve spectrometer on XRISM (and SXS on Hitomi). The same files can be downloaded directly from the XRISM FTP.

If you need help, please send your queries using the HEASARC feedback form for XRISM.

Simulation Software, Support Files, and User Guide

HEASoft (current version)

The software is part of the HEASoft suite of tools available here. The main tasks used are the following:
  heasim -- simulate an event file
  skyback -- simulate sky X-ray background
  sxsbranch -- calculate the spectrometer branching ratio
  XSPEC -- for spectra simulation
  XSELECT -- extract spectra from event file

To install the software follow the steps in the general installation directions for the HEASoft distribution.

FTP site for simulation files

The link to the left is for the FTP location of all XRISM pre-launch simulation tools described here. The following files are also available directly from the links below:
  General README -- General and more extensive README for all simulation files
  Simulation file README -- Read this file for overview information on the XRISM Resolve simulation files
      (README_XRISM_SIMULATION_v003.txt)
  Support files README -- Read this file for overview information on the XRISM Resolve simulation support files
      (README_XRISM_SPECFILES_v003.txt)
  Simulation User Guide -- User guide on performing XRISM Resolve simulations, which supplements the quick guide
      (heasim_20170825.pdf)
  Simulation files (direct download) -- This tarfile includes the support files for heasim as well as the responses and background files needed
      to simulate Resolve data and spectra (heasimfiles_20201012.tar.gz)
  heasim scripts (direct download) -- This tarfile includes the scripts that are documented in the user guide above
      (heasimscripts_20170830.tar.gz)
  Spectral files (direct download) -- This tarfile includes only those files needed for spectral (e.g., Xspec) simulations (specfiles_v003.tar.gz)
  XRISM Simulation Quick Guide -- Quick guide to performing XRISM Resolve simulations
