! ! EVN Calibration Information File - To be used with the AIPS ANTAB program ! ! Experiment : N14L1SV CO ! Date(s) : ! Waveband : 18cm. ! Stations : Py ! Comments : ! ! See the file n14l1sv co_tsys.ps on vlbeer for a plot of the Tsys in this ! experiment. ! ! N.B. You should remove from this file any GAIN curves and TSYS 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. If the INDEX lines are different for each frequency ! then you must comment out the INDEX lines in this file for the other ! frequencies. ! ! Compiled by Jun Yang (yang@jive.nl) mié 30 abr 2014 ! ! 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). The RCP DPFU is specified ! first, followed by a comma, and then the LCP DPFU. ! ! INDEX Line ! ---------- ! ! It is IMPORTANT to ensure the INDEX lines are correct. By default they are ! arranged such that the IF with the lowest frequency LCP is L1, the lowest ! frequency RCP is R1, etc. If you have any doubts about them, please contact ! the email address above for assistance. ! ! Negative TSYS values: ! ---------------------- ! ! Overflows have been replaced by -2 or 999.9 in the appropriate column and ! missing measurements by -3. These values will be ignored by the AIPS task ! ANTAB. The user should replace any other numbers that they deem inappropriate ! (very high Tsys values) 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 a brief description. ! ! TIMEOFF ! ---------- ! ! In the absence of continuous TSYS measurements, the OFFSET parameter in ANTAB ! can be used to incorporate TSYS measurements made before/after the scan. ! Since ANTAB requires that the measurement falls within the scan itself, ! OFFSET can be used to increase the apparent length of the scan. ! Alternatively, you may set TIMEOFF=90 in this file instead. This will ! displace the TSYS measurements by 90 seconds. In the case of short scans this ! number should be lowered so that the measurement falls within the scan. Try ! with lower values until ANTAB recognises the value. In most cases (especially ! when there are Tsys at both ends of the scan) OFFSET is preferable to using ! TIMEOFF. ! ! Global VLBI Experiments Correlated at Socorro ! --------------------------------------------- ! ! Global experiments correlated at Socorro may have the TSYS and GAIN ! information for the Effelsberg antenna (EB) transferred automatically with ! the data in a format suitable for use with the AIPS task APCAL (in the same ! way as the VLBA antennas). If this is the case then the TSYS and GAIN entries ! for EB should be removed from this file before running ANTAB. ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! ! PIs should carefully check TSYS values for obvious errors. ! ! ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! ! Amplitude calibration data for SV in n14l1. !
