Today's time is well calibrated, well thermalized.
We can see New peaks in the the ASD, and some of our old peaks are higher. From 10-15hz, 25-30hz, 500- 600HZ, 2k hz esp.
We seem to also have a broadband decrease in both sensitivity and range. Where our sensitivity loss is small at most frequencies, but spans a wide frequency range.
Unfortunately our range has dropped off from 80hz -2k  hz by up to ~15 Mpc. See first page.
The good news is that there are some very slight gains in range in the 50-80 hz freq range. See 3rd page
