COVER LETTER:


This is the schedule for the 18cm ftp fringe-test on 28 May 2018
involving 11 antennas. JB2, WB1, EF, MC, ON85, TR, SV, ZC, BD, HH, SR.
The NME uses 16x BBC (8 for each Pol.) of 8MHz bandwidth: Data rate of 512 Mbps.

The schedule consists of:
- long integrations on a strong calibrator:
3C84
for ftp-fringe tests;

Ftp-fringe tests are scheduled every 15 min throughout the experiment:
11:05:00 (scan 2, 2 sec, 3C84)
11:20:00 (scan 4, 2 sec, 3C84)
11:35:00 (scan 6, 2 sec, 3C84)
11:50:00 (scan 8, 2 sec, 3C84)


All the best to everyone involved

Katharina

  UP:  D => Below limits;  H => Below horizon mask;  W => still slewing at end;  blank => Up.
  Early: Seconds between end of slew and start.   Dwell: On source seconds. 
  Disk: GBytes recorded to this point.
  TPStart:  Recording start time.  Frequencies are LO sum (band edge).
  SYNC: Time correlator is expected to sync up.

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) 
   3C84                23.7
   0528+134            18.6

  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 
      15.0 GHz         12. deg 
      22.0 GHz          9. deg
