Comparing Wiener subtraction with different seismometers
Attached is a plot of MC_L, and then the residual MC_L after static Wiener filtering, using different combinations of our accelerometers and seismometers.
This is the same type of plot that Rana has included in the past few weeks, using Wiener filters calculated with c1wino.m
This data is from GPS 912312914, duration = 7200 sec, sometime during the night last night.
Unfortunately, it doesn't look like adding the Guralp seismometer to the Accelerometers and the Ranger did much, especially at low frequencies (all sensors = black curve). We'll have to investigate why this is true, and what we can do to get some low-frequency subtraction going on.
In the legend, "Residuals Accels, Guralp, Ranger" implies that the residual has been calculated using all of the sensors listed.
