Print this reportDoes SHINDO monitor at Atotsu work?K1:PEM-SEIS_ATOTSU_GND_SHINDO sometimes makes SDF differences as shown in Fig.1.
In almost all time, it shows -0.161506. But it sometime shows large value (see also Fig.2). I'm not sure it works properly with poorer sensitivity than another seismometer or doesn't work with some problem on computing seismic intensity. So I cannot decide how to treat this channel. Please process this channel in order to go to CALIB_NOT_READY or higher.

Print this reportI checked all channels which managed by the k1pemmanage model. Web for the k1pemmanage model : here
From this point
K1:PEM-DONT_REMOVE(1,2)_* Those channels would be necessary to keep the real time model. Any effect would be there for those channels, so I want to ask expert to keep monitor or not.
K1:PEM-*_SHINDO There are several more channels about the SHINDO monitor from klog34007. All channels can be seen in Fig.1. As you know SHINDO varied with time, could you remove them from monitor channel in observation state?
K1:PEM-TEST(1,2,3,4) I didn't remember the motivation, we didn't use them. So it would be better to keep monitoring during observation run.
K1:PEM-SNOW_* They are snow depth monitor channels. Currently, we are removed the snow monitor, but there are possibility to change value if snow monitor recovered and snow happened. So could you remove them from monitor channel in observation state?
K1:PEM-WATER_* It would be better to ask Washimi-san, but they are the monitor channel for EY water flow. So could you remove them from monitor channel in observation state?
K1:FEC-73_* I cannot judge those channels.
Current full channels can be seen in Fig.2.

Print this reportThank you for clarifying. I removed sensor readouts (SHINDO, SNOW, and WATER) from the monitored channel list by SDF (see also klog#34047). Another channels e.g. K1:FEC-* are kept in the monitored channel list same as other models.
