Decimation was active/vigorous for the full time period, with the SSR level currently at around 30%.
Detectors 1, 3, 6, and 8 are recording events. The cold tips are about 128K as of July 19, and cold plates are at about 153K. Cryocooler power is steady at 75.6W, for recent tmperatures, cryocooler efficiencies, and accelerometer values see:
Detectors 1, 3, 6, and 8 are powered on, and are recording events. No detector operations this week.
On 2017-194-19:50:11 UTC (July 13, 2017), the attenuator thresholds were changed, to reflect a new background of 17.1% deadtime.
