!  BB184A: December 12 12-22UT, VLBA+GB+EB NGC6323 via phase referencing
!  Incl. two blocks of atmospheric delay calibrators obsd over a range of elv.
!
! 256 Mbps, 2 tapes/station.  POSTPASS at EB must be prevented.
! 
! Line source:
!   Strongest emission appears 7320-7420  7800-7950  8200-8400 opt/LSR
!   Use 4x16MHz bands (215 km/s each).
!		
! Scan layout:
!  Phase reference calibrator: 1709+431 (Braatz monitoring ~ 0.2 Jy c2005)
!  Delay calibrator:  1739+522 (NRAO monitoring ~ 1.5 Jy c2005)
!  Bandpass calibrators: 3C345 (resolved) - 1739+522 may have to do.
!                        No other good options w/ good mutual visibility.
!  NGC6323 Pointing  :  1739+522 (GB) 3C345? (EB)
!  
!  11 minutes is available every 50 min for GBT/EB pointing.
!  No VLBI scan is more than ~41m from the end of a pointing scan 
!
!  Cycle:
! 			+0m	5.5m VLBI calibrator
!				1m   slew	
!			+6.5m   50s  1709+431

!                       +       50s  1709+431

!                                    VLBA continues cycle 
!			---------------------
!		        +50m  
! There are only two exception to this cycle, when observing the 
! bandpass calibrator and when changing tape at EB.
! Time on source for NGC6323 ~2.4h at VLBA stations. 
! Time on source at GBT/EB is difficult to estimate, but is likely
! down by about a factor of ~ two.  In 2.4h, the VLBA can achieve ~6 mJy
! in a 62.5 kHz channel.  Over 10 km/s, we may expect 1.7 mJy.  Ideally,
! GBT/EB will reduce this by at least a factor of 4. Compensating for 
! lower observing time on those baselines, I estimate the reduction will
! may be on the order of 2. Conservatively, we may anticipate 1 mJy noise.
! over 10 km/s.
