! Comments   : N.B. You should remove from this file any antenna gain curves 
!              for antennas for which you have no data.
!              N.B. Also check that the index lines for each antenna are
!              correct for this experiment/data format.
!              N.B. If this experiment involves more than one frequency, you
!              must run ANTAB once for each frequency, commenting out the gains
!              in this file for the other frequencies.

! Polarization 
! ------------
!
! If there is only one polarization available this is indicated by having 
! DPFU value 0.0 for RCP (0.0 for LCP for S and X Band).
!
! INDEX Line
! ----------
! 
! It is IMPORTANT step to ensure the INDEX lines are correct. If you have any
! doubts about them, please contact the email address above for assistance.
!  
! Negative TSYS values:
! ----------------------
!       
! Overflows have been replaced by -2.0 in the appropriate column and empty 
! columns by -3.0. The user should replace these numbers and others that they 
! deem inappropriate (very high Tsys values and occasional negative numbers) 
! with appropriate numbers from adjacent scans or IFs. Some interpolation may
! already have been done by the producer of this file; see the comment line 
! above for brief comments.
!
! TIMEOFFSET 
! ----------
!
! The TIMEOFFSET is used as EVN makes the TSYS measurements before the scan. 
! Since ANTAB requires that the measurement falls within the scan itself 
! TIMEOFFSET=90 is used. This will displace the measurement by 90 seconds. In 
! the case of short scans this number should be changed so that the measurement 
! falls within the scan (TIMEOFFSET needs to be lowered). Try with lower values 
! until ANTAB recognizes the value. Alternatively, you may set TIMEOFFSET  to 0
! and use the option 'OFFSET' in ANTAB instead to increase the effective 
! length of the scans.

!    PIs should  carefully check TSYS values for obvious errors.    !
