This afternoon I recentered BRS-Y. I've managed to get it in a good location with the "DC" position at about 5000 counts (out of +/- 16000 counts). After getting to thermal equilibrium it should be something more like 8-10k counts, looking at trends the drift has slowed to maybe -200 cts/week, giving us (8k+16K total range) / 200 cts/wk = 120 weeks before I have to do this again. Please.
