Captured spectra for ranges at 140Mpc to 155Mpc, as well as the spectra after SR3 aligment changed to 83 from 438.
Reference point are labeled. The file is saved at /ligo/home/karmeng.kwan/DARM_trace.xml
DARM spectra was captured from H1:CAL-DELTAL_EXTERNAL_DQ
No clear differences seen between the spectra before and after the SR3 alignment change.
The comparison of the spectra shows the excess noise at 20-25Hz regime contributes to range drop, for both the original alignment and after SR3 alignment change.
