EFFECT OF SOLAR CORONA

  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) 
   NGC235A             67.9
   NGC7603             74.6
   J0040-2340          68.5
   J2319+0018          74.5
   J2253+1608          75.0

  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
