Overview

This page is for distribution of pulsar timing models made by the LAT team directly from LAT gamma-ray data, independent of any radio timing data that may exist. We use the methods documented in Ray, Kerr, Parent et al. (2011, ApJS, 194, 17, arXiv:1011.2468). The primary focus is on the blind search pulsars and other pulsars that are not easily timed in the radio or X-ray bands. If you would like a particular pulsar added to this page, please contact us. This work is being supported by the Fermi Cycle 3 Guest Observer program.

You are free to use these LAT timing solutions to fold your data. If you publish work based on these models, please reference Ray, Kerr, Parent et al. (2011) and this page in your publication. The primary intent is to support pulsar analyses requiring timing ephemerides, such as phase-resolved spectroscopy and analyses of sources close to bright pulsars through the use of pulsar `gating'.  If, on the other hand, you want to publish something based on the values of the timing model parameters (e.g. timing positions, glitch parameters, etc...) we ask that you contact us first because there may be important caveats or publication plans.

Latest models are available HERE

Models will be updated every 3-6 months, or sooner if requested.

List of Pulsars that have a LAT timing model

Note that not all of these pulsar will have up to date models depending on when we last ran them. If you have a need for one, just let us know.
