TL;DR: In this article, a model emission mechanism is used to interpret the limits as a constraint on the pulsar's equatorial ellipticity, and two independent analysis methods are used and are demonstrated in two independent methods: a frequency domain method and a time domain method.

TL;DR: The unprecedented sensitivity of the detectors allows us to set strain upper limits as low as a few times 10(-24), which translate into limits on the equatorial ellipticities of the pulsars, which are smaller than 10(-5) for the four closest pulsars.

TL;DR: In the analysis of the adaptive feedforward methods, it is concluded that the popular filtered-x LMS algorithm is useful for implementation, but is best analyzed from a classical linear time invariant feedback perspective.
