Data Challenge 1: Closed Data Set Parameters

Dataset 1: Uniformly sampled data with a stochastic GW background and white noise

  • White Noise: 100 nano-seconds for each pulsar
  • GW Background: Characteristic strain spectrum is a power law with index -2/3. The amplitude of the strain spectrum at a frequency of   1 year-1 is 1 x 10-14
  • Cadence: Once every two weeks
  • Total Time Span: Five Years

Dataset 2: Non-uniformly sampled data with a stochastic GW background and white noise

  • White Noise: Different for all pulsars, consistent with measured values of residuals for IPTA pulsars. Click here to get the list of the white noise RMS for each pulsar.
  • GW Background: Characteristic strain spectrum is a power law with index -2/3. The amplitude of the strain spectrum at a frequency of 1 year -1 is 6 x 10 -14
  • Cadence: Randomly sampled. Average interval of two weeks, ±5 days. Same time base for all pulsars
  • Total Time Span: Five Years

Dataset 3: Non-uniformly sampled data with a stochastic GW background together with white and red noise

  • White Noise: Same as in dataset 2
  • Red Noise: Same power spectrum for all pulsars, different realization

Red Noise Power Spectrum is of the form: P(f) = A f where f is in Hz, A = 3.66 x 10-18 seconds1.8 and  α= 1.2.

  • GW Background: Characteristic strain spectrum is a power law with index -2/3. The amplitude of the strain spectrum at a frequency of 1 year-1 is 5 x 10-15
  • Cadence: Randomly sampled. Average interval of two weeks, ±5 days. Same time base for all pulsars
  • Total Time Span: Five years
