their signals (also shown unprocessed in the paper) look convincing. At one detector, the as-expected shape would be quite puzzling, and at both detectors with the proper lag it's just believable.

This signal appeared quickly within a few weeks observation time. Meanwhile Ligo worked for months. They probably have more detections, to be announced in following papers.

One more Ligo is planned in India, would be nice to determine the source direction - though one more, deep in the southern hemisphere, would be even better - and Virgo shall enter service in the Advanced version this year I bet Lisa will pick momentum €€€ now.
