Last year, we thought we had found a configuration using sensor correction on HEPI that worked on HAM3. I was looking (Krishna was, too, he saw it first) at the summary pages over break and noticed that HAM3 still looked like it had the .6hz peak. I came in this morning, checked the configuration and did an on/off measurement, and HAM3 still has the same issue, even when we correct to HEPI instead of the ISI, contrary to what we found last time. See attached plot. Solids are measurement taken with sensor correction off, dashed are with HEPI sensor correction.
Which ground siesmometer was used for the sensor correction?
