Swift-XRT Monitoring of Fermi-LAT Sources of Interest

The results presented on this page are from a preliminary analysis of the Swift-XRT data. The analysis procedure is described in this README file. Since the analysis is performed using automated scripts and the results are not always reviewed by human eyes, we recommend that these data be reviewed by hand before use in publications.

For questions or requests for more detailed analysis, please contact Abe Falcone and Michael Stroh at monitoring@swift.psu.edu. This web site is under construction so please report any web site related problems to the email address listed above.
