The T240 on the floor still looked well centered this morning so I opened the BRS thermal house, pulled the STS2 and installed the T240. Wrapped it up in an ad hoc thermal blanket; maybe the low end will be even better for it.
Couple photos attached. Will post some data after a few hours or tomorrow--likely will need a mass centering as this will be a different temp environment for the instrument.
Addition: the channels are:
X == H1:PEM-EY_ADC_0_09_OUT_DQ
Y == H1:PEM-EY_ADC_0_10_OUT_DQ
Z == H1:PEM-EY_ADC_0_19_OUT
That's right, the Z signal has no DQ variant.
