The results of the calculation are then compared to ALLEGRO's sensitivity limit. |
The thesis you cite, dated 2003, is an exposition on why Allegro failed. If you look at the papers while Allegro was being designed, and even
during testing, you read:

Verry specifically, they expected to be able to see gravity waves from Relativistic binary Pulsar B1913+16 within our own galaxy. It would be interesting to compare Taylor’s initial calculations, predicting Allegro would be sensitive enough to detect galactic events, with Santostasis’s post mortem that explains why we did not, and see how and why parameteric assumptions were tweaked. More, later.
