They leveraged public data products from the LIGO-Virgo-KAGRA Collaborations' 3rd and 4th observing runs to show that there are non-trivial temporal variations within the detection probability that are well-described by a weekly cycle. There are clear differences between weekends and weekdays, between day and night (at the sites), and even between daylight-savings and standard time.
