CD: No data after about 16:00 (FS computer crashed).
HO: Ho low sensitivity especially in LCP. Suspected problem with 6.7 GHz receiver. Also about 5% data missing due to disk failure.
HB: Hb was put on schedule from 05:57 as backup to Ho. Less sensitive than Ho RCP and comparable to Ho LCP, so unlikely to be very useful but included in correlation anyway.
AT: Clock jump at approx. 2021y126d06h36m00s
Correlator: CALC9 used.
