The STS-2 at the corner station is currently installed by BSC4 (under the stairs). Since the STS-2 is relatively "far appart" from the BSC1 and BSC2 chambers, I checked the coherence from the STS-2 and the T240s installed in stage 1 of the ISIs. Plots of coherence are presented in attachment. Coherence is really good (in the 100mHz to 3Hz frequency band) but not as good as the end station where the STS-2 is closer from the chamber. Coherence between the stage 1 of the 2 ISIs is also presented.
