COVER LETTER:



This is the schedule for the 18cm NME and ftp fringe-test on 27 May 2021
involving the following antennas:
Jb1, Wb, Ef, Mc, Nt, On85, T6, Ur, Tr, Hh, Sv, Zc, Bd, Ir, Sr, Cm, Da, De, Kn, Pi.

The NME uses a standard setup with 1024 Mbps.

The schedule consists of long integrations on calibrators J0956+2515.
The following ftp-fringe tests are scheduled throughout the experiment (UT times):

12:10:00 (scan 2, 2 sec, J0956+2515)
12:40:00 (scan 4, 2 sec, J0956+2515)
13:10:00 (scan 6, 2 sec, J0956+2515)
13:40:00 (scan 8, 2 sec, J0956+2515)
14:10:00 (scan 10, 2 sec, J0956+2515)
14:40:00 (scan 12, 2 sec, J0956+2515)


Good luck with the session!

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) 
   J0956+2515          76.7

  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
