  UP:  D => Below limits;  H => Below horizon mask.  blank => Up.
  Early: Seconds between end of slew and start.   Dwell: On source seconds. 
  Tapes: Drive, Index, Start footage / Direction, Head Group, End footage.
         For disks, the footages are really the GBytes
  TPStart:  Tape motion start time.  Frequencies are LO sum (band edge).
  SYNC: Time correlator is expected to sync up.

  The solar corona can cause unstable phases for sources too close to the Sun.
  SCHED provides warnings at individual scans for distances less than 10 degrees.
  The distance from the Sun to each source in this schedule is:
    Source         Sun distance (deg) 
   M15                102.6
   3C345              117.8
   J2123+1007         105.0
   J2139+1423          99.6
   CTA102              88.9

  Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes 
  that the Sun will cause amplitude reductions on the  longest VLBA baselines 
  at a solar distance of 60deg F^(-0.6) where F is in GHz. 
  For common VLBI bands, this is: 
       327 MHz        117. deg 
       610 MHz         81. deg 
       1.6 GHz         45. deg 
       2.3 GHz         36. deg 
       5.0 GHz         23. deg 
       8.4 GHz         17. deg
