.. _xray_data_README: Auxiliary Data Files for use with yt's Photon Simulator ======================================================= Included in the `xray_data <https://yt-project.org/data/xray_data.tar.gz>`_ package are a number of files that you may find useful when working with yt's X-ray `photon_simulator <photon_simulator.html>`_ analysis module. They have been tested to give spectral fitting results consistent with input parameters. Spectral Model Tables --------------------- * tbabs_table.h5: Tabulated values of the galactic absorption cross-section in HDF5 format, generated from the routines at http://pulsar.sternwarte.uni-erlangen.de/wilms/research/tbabs/ ARFs and RMFs ------------- We have tested the following ARFs and RMFs with the photon simulator. These can be used to generate a very simplified representation of an X-ray observation, using a uniform, on-axis response. For more accurate models of X-ray observations we suggest using MARX or SIMX (detailed below_). * Chandra: chandra_ACIS-S3_onaxis_arf.fits, chandra_ACIS-S3_onaxis_rmf.fits Generated from the CIAO tools, on-axis on the ACIS-S3 chip. * XMM-Newton: pn-med.arf, pn-med.rmf EPIC pn CCDs (medium filter), taken from SIMX * Astro-H: sxt-s_100208_ts02um_intall.arf, ah_sxs_7ev_basefilt_20090216.rmf SXT-S+SXS responses taken from http://astro-h.isas.jaxa.jp/researchers/sim/response.html * NuSTAR: nustarA.arf, nustarA.rmf Averaged responses for NuSTAR telescope A generated by Dan Wik (NASA/GSFC) .. _below: Other Useful Things Not Included Here ------------------------------------- * AtomDB: http://www.atomdb.org FITS table data for emission lines and continuum emission. Must have it installed to use the TableApecModel spectral model. * PyXspec: https://heasarc.gsfc.nasa.gov/xanadu/xspec/python/html/ Python interface to the XSPEC spectral-fitting program. Two of the spectral models for the photon simulator use it. * MARX: https://space.mit.edu/ASC/MARX/ Detailed ray-trace simulations of Chandra. * SIMX: http://hea-www.harvard.edu/simx/ Simulates a photon-counting detector's response to an input source, including a simplified models of telescopes.
