Mock LISA Data Challenge
Round 1 - Data Sets
These are the original datasets for MLDC Round 1 which was completed on Dec 4, 2006. The key files with information about the sources included in the blind challenge data set are now available here. Complete information on the Round 1 challenges, including the LISA model, the source models, and the parameter range specifications are discussed in Sixth LISA Symposium (Overview,HOW-TO) and in the Round 1 challenge specification document.
Challenge 1.1 - Galactic White Dwarf Binaries
Challenge 1.1.1 - Single Galactic Binaries
- a) 1 year of Gaussian stationary instrument noise + 1 exactly monochromatic WD with SNR ~10 ->20 over 1 year (for single IFO) at frequency 1.0+/-.1 mHz

1 year of Gaussian stationary instrument noise with 5 true verification binaries (parameters chosen according to our current best guess) + 15 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 will be given. 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 1.1.4 - Source Confusion* (LISA Simulator Training data were corrected 26 Oct 2006.)
1 year of Gaussian stationary instrument noise with 40 < N < 60 WD binaries chosen with frequencies f in a narrow band ( 3.000 mHz < f < 3.015 mHz ) and with SNR > 5. Sources are drawn from the BLT population synthesis code. All the signals will be monochromatic (no fdot). The number of sources will not be given.

Challenge 1.1.5 - Strong Source Confusion
1 year of Gaussian stationary instrument noise with 30 < N < 50 WD binaries chosen with frequencies f in a very narrow band ( 2.9985 mHz < f < 3.0015 mHz ) and with SNR > 5. Sources are drawn from the BLT population synthesis code. All the signals will be monochromatic (no fdot). The number of sources will not be given.

Challenge 1.2.1*
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.
