SOURCE SCAN SUMMARY FOR SOURCES LISTED ABOVE

     Scan hours are for recording scans only. 
     Baseline hours are only counted for scans above horizon at both ends.
     'Core' scans are those for which PREEMPT is not 'EXTRA'.
     The 'DOSCANS' columns are for scans in the range selected by DOSCANS
     Those are the scans sent to the Vex and other files

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)

   J1532+2344         108.3

  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:
