GBM Accreting Pulsar Histories

For each source we plot the history of pulse frequency and pulsed flux measured using the Fermi Gamma-Ray Burst Monitor (GBM) NaI detectors. For these measurements we use the CTIME data which normally has 0.256 s time bins, and eight energy channels. Our analysis normally uses channels 1 (12-25 keV) and 2 (25-50 keV). The integration interval used varies from source to source, ranging from one to four days. For eclipsing systems each egress to ingress interval is divided into an integral number of equal parts, with no measurement made during the eclipse. The measured frequencies are barycentered. For sources where the binary orbit is known, the frequencies are corrected for the binary motion. The R.M.S. pulsed flux is given in the energy band in which the pulse search was made. This usually includes only the first and second harmonics. These results are preliminary.

We are now offering custom searches for pulsations for all of our catalogued sources. You may specify the energy band, frequency band, frequency derivative band, time range, integration time, ephemeris and harmonics to be searched. We will also accept searches for pulsations for non-catalogued sources. The results will include best frequency/derivative where detected, pulsed flux or upper limits where not detected, phase if an ephemeris is used and pulse profiles for each energy band. Please send an email request to Peter Jenke.
