Comments:

(1)  Traditional fringe-verification test. This specific 3-hour interval was recommended by the GTG.  Note
     that this time this will take place 1 day before observations start, after consultation with the
     telescopes.

(2)  Nominal period for station amplitude calibration, as requested by the GMVA Technical Group (GTG).
     The actual period when amplitude calibration is performed can be chosen by each individual observatory.
     Antenna temperature measurement of a suitable planet or other primary flux calibrator is recommended.

(3)  Requested 5hr assuming a duty cycle of 75%, time extended to 07:00 to 17:00 UT, for European starting
     at 03:00 since the source is circumpolar.
