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 0.89 duty cycle and SNR threshold: 7.0

Conducting monte-carlo over 2000 trials, randomizing sky position and orientation.
