+STATION_NOTES

HOBART12 (Hb/d): A few G-codes due to lower signal amplitude in the

                last two channels of the S-band.

KATH12M (Ke/a): Missed scans from UT 293-1934 to UT 293-2032, because

                FS had to be resynced.

YARRA12M (Yg/i): Ok.

Problems: Several clock breaks at Hobart12. Breaks set at 00:33

        (-3.44 nsec) and at 11:52 (-.67 nsec). Also the scans 
        from ~22:23-22:56 on the HB baselines are offset by 
        ~.7 nsec and were deselected.
        There may be one or two breaks at Yarragadee, but they
        are not so clear and applying one did not help. The 
        clock constraint was relaxed instead to 6.E-14.

Parameterization comments: None.

Other comments: Hart15m reported bad refraction corrections for

        the first 14 hrs, but the data looks okay.

• Recoverable: can be included in the solution.
• * Total includes distinct observations only.

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,
           but the analyst rejected it all.
