With improvements in the past couple of months in the low frequency noise on both interferometers, and both now capable of achieving 160+ Mpc BNS range, I wanted to make a current comparison of the low frequency noise between H1 and L1 -- see the attached plot. For each interferometer, I selected a recent time where its BNS range was at/near its maximum, which is between 160-165 Mpc. The strain noise levels are nearly identical above 45 Hz. Below that, L1 has lower noise, by factors of 2-3 in the 10-30 Hz band.
