 Here's a plot of the spectra of the seismometers and MCL. The coherence shows which axes are aligned right now: MC1_X is coherent with GUR_NS which means that its mis-oriented.

I've now swapped the "MC1" cables: so the old "NS" now goes into EW and the old EW now goes into NS. VERT is unchanged.

Also fixed the channel names - the Guralp previously named MC1 is now GUR1 and the other one is GUR2. Also no more EW, NS, & VERT. Its all XYZ.

DAQD restarted with the new channel names.

 I spiffed up the order of the cables / sensors plugged into the PEM ADCU.  Now all of the seismometers are labeled as Rana left them, and the 2 Guralp's have their sets of 3 channels next to eachother in channel-number-land.  None of the accelerometer names/cabling have changed recently.  In the table, Cable-label refers to the physical tag tied to the end of the cables plugged into the ADCU...they are meant to be descriptive of what seismometer channels they are hooked up to, and then the names change to something useful for us when they come into the DAQ system.  Also, the labels of input channels on the ASS_TOP_PEM screen have been updated accordingly.

 

Channel Name Channel Number on ADCU and OAF PEM list Cable-label .ini channel number
C1:SEIS-GUR2_X 2 Gur2 EW 15001
C1:SEIS-GUR2_Y 3 Gur2 NS 15002
C1:SEIS-GUR2_Z 4 Gur2 Vert 15003
C1:SEIS-GUR1_X 10 Gur1 EW 15009
C1:SEIS-GUR1_Y 11 Gur1 NS 15010
C1:SEIS-GUR1_Z 12 Gur1 Vert 15011
C1:SEIS-RANGER_Y 24 Ranger
