AtomDB Downloads
We no longer require registration to download AtomDB. However we would be grateful if you would leave your contact details with us so we can notify you of future releases, updates, or corrections. It is also useful for our statistics to see how widely used AtomDB is: we will not share your details with anyone. You can register here.
Fe IX data (July 5th 2011)
If you are looking for the Fe IX data from this paper, please contact us for the link. The dataset will be included in AtomDB v2.1.0 when it is released, but you can see it now if you wish.
AtomDB 2.0.1 Release (June 22nd 2011)
A bug has been discovered in version 2.0.0 of AtomDB which has required the release of version 2.0.1. We apologize for the mistake, and strongly encourage all users to upgrade now.
There are two different versions of the dataset, for compatibility reasons. As of version 12.7 (June 2011) XSPEC can handle the full new version of AtomDB. If you are still running an older version of XSPEC you will have to use the 14-element only XSPEC_LEGACY version of AtomDB.
All three of these files will unzip into a folder atomdb_v2.0.1. Some files are duplicated in all tarballs, for example the RELEASE_NOTES. The VERSION file is different for the XSPEC_LEGACY tarball, if you wish to use the XSPEC_LEGACY version make sure you untar it last.
atomdb_v2.0.1_runs.tar.gz - line, continuum and linelist files (14MB) md5sum
atomdb_v2.0.1_xspec_legacy_runs.tar.gz - line, continuum and linelist files, restricted to the 14 elements in v1.3.1 (12MB) md5sum
atomdb_v2.0.1.tar.gz - all the underlying atomic data (e.g. energy levels, collision strengths, etc) (130MB) md5sum
In addition, following requests from users we have produced a run which extends the spectrum from an upper limit of E=50keV to E=100keV:
atomdb_v2.0.1_100kev_runs.tar.gz - line, continuum and linelist files (14MB) md5sum
atomdb_v2.0.1_100kev_xspec_legacy_runs.tar.gz - line, continuum and linelist files, restricted to the 14 elements in v1.3.1 (12MB) md5sum
AtomDB IDL Tools
In addition, we have created a number of utility routines that read and manipulate the ATOMDB, including IDL routines that can read the files and create model spectra. These can be downloaded here:
Both Sherpa and XSPEC can now read spectral files created by APEC. The APEC output routines are a separate library, called fitsspec, available here for those potentially interested in creating their own spectral output files. Please contact us if you are interested in using these or need any help with them:
Previous Versions
AtomDB 2.0.0 (January 10th 2011)
The full release of version 2.0.0 is now available. The beta test has been completed without any major issues being found, but please let us know if you find any.
A paper is being prepared listing the changes in detail. An early draft of this, warts and all, is here. This will be updated as the paper progresses.
There are two different versions of the dataset, for compatibility reasons. XSPEC assumes the AtomDB data has 14 elements present. This can be easily changed within the XSPEC source, but we provide here a version with the same 14 elements as version 1.3.1 for comparison purposes.
All three of these files will unzip into a folder atomdb_v2.0.0. Some files are duplicated in all tarballs, for example the RELEASE_NOTES. The VERSION file is different for the XSPEC tarball, if you wish to use the XSPEC version make sure you untar it last.
atomdb_v2.0.0_runs.tar.gz - line, continuum and linelist files (15MB) md5sum
atomdb_v2.0.0_xspec_runs.tar.gz - line, continuum and linelist files, restricted to the 14 elements in v1.3.1 (12MB) md5sum
atomdb_v2.0.0.tar.gz - all the underlying atomic data (e.g. energy levels, collision strengths, etc) (76MB) md5sum
