! ! EVN Calibration Information File - To be used with the AIPS ANTAB program ! ! Experiment : C1004 ! Date(s) : ! Wavelength : ! Stations : Sh ! 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. ! ! Compiled by Cormac Reynolds (reynolds@jive.nl) ! Version: newantab.pl - October 2000 ! ! Send any changes or updates to the antenna information or queries about this ! file to the email address given above ! ! 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 Overflows have been replaced by -2.0 in the appropriate column and empty !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. ! ! ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! / ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !GAINS at 13cm ! ! !
