Capability to detect a resolved stellar-mass source out to specific horizon distances
Summary
Plot of distance out to which LISA binaries can be detected as a function of GW frequency.
We have assumed 4.5 yr years of observation with 0.82 duty cycle and SNR threshold: 7.0
Conducting monte-carlo over 2000 trials, randomizing sky position and orientation.
