Mock LISA Data Challenge
Round 1B - Data Sets
Round 1B is now compeleted The key files linked below. You can see the submissions hereRound 1B is a re-issue of the Round 1 challenges to provide new groups an opportunity to develop their codes, while experienced groups work to improve their algorithms. Though the sources are drawn from the same distributions as in Round 1, the codes used to generate the datasets are those of Round2. Round 1B will terminate in December 2007. Submit your results here.
For further information about the challenges, see the MLDC How-to produced for round 2.

Challenge 1B.1.2 - Verification Binaries
1 year of Gaussian stationary instrument noise with 5 true verification binaries (parameters chosen according to our current best guess) + 20 mock verification binaries in the frequency range 0.5 mHz - 12 mHz. All the signals will be monochromatic (no fdot). Since these are verification binaries, the sky locations and orbital frequencies are given (here). The orientation parameters and distances will be considered unknown.

1 year of Gaussian stationary instrument noise with 20 resolvable binaries (parameters chosen from the BLT population synthesis code) with frequencies spread over the LISA band. All the signals will be monochromatic (no fdot).

Challenge 1B.2 - MBH Binaries
Challenge 1B.2.1
1 year of Gaussian stationary instrument noise + 1 Schwarzschild SMBH binary with time to coalescence 6(+/-1) months and masses m1 1-5 million solar masses and m2 = m1/x, where 1 < x < 4 . The signals have SNR for one IFO in the range 450 < SNR < 500 . The waveform model for the inspiral is restricted to the 2PN approximation with no spin-orbit nor spin-spin modultations.

Challenge 1B.3 - EMRIs
Each of the 5 elements of Challenge 1B.3 includes precisely one EMRI source in a ~2-yr long (to be precise: 2^22 data points with cadence 15 seconds) data set. For each case, the EMRI parameters more reduced mass, spin of the central black hole, eccentricity and duration are drawn as follows: mu/M in U[9.5, 10.5], S/M2 in U[0.5, 0.7] time at plunge in U[2^21, 2^22] x 15 sec, and eccentricity at plunge in U[0.15, 0.25]. The mass of the central black hole varies.
