Location in the Galaxy
The figure below displays the position of accreting X-ray pulsars in the Galaxy as far as known at this moment. Click on the figure for a larger version. Labels indicate the ordinal number in the first column of the table. Uncertainties in the distances are not indicated. Empty symbols represent sources for which there is no distance info in the literature; they have been artificially set to a distance of 7.6 kpc. [source class identifiers] are also given. The spiral arms are from [(:biblio:Vallee08)]. Figure and data provided by Arash Bodaghee, SSL, UC Berkeley.

Correlation between luminosity and CRSF energy
In recent years more and more sources have been observed at different luminosities, allowing us to find correlation between the luminosity and the cyclotron line energy. A summary of the current state of the observations can be found on this page: CRSF energy as function of luminosity
Assignments
Our collaboration has assigned one or two sources to each member ro take care of, i.e., to put together the most important information and keep the page up to date in case new data are available or new papers are published. The list can only be accessed if logged in.
