H1 ISI CPS Noise Spectra Check - Weekly FAMIS 25972

FAMIS 25972

BSC high freq noise is elevated for these sensor(s)!!!
    
ITMX_ST2_CPSINF_H1    
ITMX_ST2_CPSINF_V1

The Primary Microseism is currently elevated in a strange way, which may explain a slight increase in the noise Spectra across all chambers. But other than that I did not see anything that looked wildly different from the last ISI CPS Noise Spectra Check referenced in alog 75088.
