periodic thump noise in MC1_ACC |
|
|
There seems to be a periodic thump seen by the MC1 Accelerometers as well as the surrounding optics.
The first 5 hour minute-trend plot shows the periodic thumping as well as the one large saturating event which ruins the
Wiener noise subtraction.
The second plot is a 30 minute second-trend zoom in. |
