 + ​HOBART12 (Hb/d): Missed scans:
 +                  from UT 300-2210b to UT 300-2241, ​
 +                  at UT 300-2320a, UT 300-2325b and UT 300-2327,
 +                  at UT 301-0040, UT 301-0046 and UT 301-0050, ​
 +                  from UT 301-0124 to UT 301-0712
 +                  due to windstow.
 +
 +                  Note that some of the above scans contribute to the 
 +                  statistics as non-detections.
 +
 + ​KATH12M ​ (Ke/a): Ok. 
 +
 + ​YARRA12M (Yg/i): Ok. 
 +
 +Problems: Hobart12 had several windstows, one lasting ~6 hrs. 
 +          The cable cal at NYALES20 was unstable, with 2 breaks.
 +          It was not applied. This has happened several times
 +          recently and is being investigated. ​
 +
 +Parameterization comments: None. 
 +
 +Other comments: None.

 +  MISSED: ​   Station was scheduled, but it did not observe.
 +  NOT CORR:  Station was scheduled but not correlated.
 +  NOT USED:  Usable data was generated for this station,
