Auxiliary Data Files for use with yt’s Photon Simulator¶
Included in the xray_data package are a number of files that you may find useful when working with yt’s X-ray photon_simulator analysis module. They have been tested to give spectral fitting results consistent with input parameters.
Spectral Model Tables¶
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)
Other Useful Things Not Included Here¶
FITS table data for emission lines and continuum emission. Must have it installed to use the TableApecModel spectral model.
Python interface to the XSPEC spectral-fitting program. Two of the spectral models for the photon simulator use it.
Detailed ray-trace simulations of Chandra.
Simulates a photon-counting detector’s response to an input source, including a simplified models of telescopes.
