COVER LETTER:

This is the schedule for the 13cm NME FTP-FT on 11 June 2024
involving the following 6 antennas: Wb1, Ef, Mc, Nt, On60, Hh.

The NME uses a 64-Mbps setup (2 BBC, 32-MHz, dual polarization),

The NME lasts for 3 hours (12:00-15:00 UT) with scans on calibrators:

J0854+2006 (OJ287)   -- https://obs.vlba.nrao.edu/cst/calibsource/6716

with ftp grabs every other scan at the following times (in UT):
12:10:00 (scan  2, 2 sec, J0854+2006)
12:40:00 (scan  4, 2 sec, J0854+2006)
13:10:00 (scan  6, 2 sec, J0854+2006)
13:40:00 (scan  8, 2 sec, J0854+2006)
14:10:00 (scan 10, 2 sec, J0854+2006)
14:40:00 (scan 12, 2 sec, J0854+2006)
14:59:00 (scan 14, 2 sec, J0854+2006)

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) 
   J0854+2006          49.8

  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

       5.0 GHz         23. deg 
       8.4 GHz         17. deg
