! ! EVN Calibration Information File - To be used with the AIPS ANTAB program ! ! Experiment : F02L1 ! Date(s) : ! Waveband : 18cm ! Stations : ArEfMcOnShTrUrWb ! Comments : ! ! See the file f02l1_tsys.ps on vlbeer for a plot of the Tsys in this ! experiment. ! ! 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. If the INDEX lines are different for each frequency ! then you must commenting out the INDEX lines in this file for the other ! frequencies. ! ! Compiled by Cormac Reynolds (reynolds@jive.nl) Wed ! Version: newantab.pl - 23 Apr 2002 ! ! 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 Overflows have been replaced by -2 in the appropriate column and missing !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 TIMEOFF keyword can be ! used to incorporate TSYS measurements made before/after the scan. Since ANTAB ! requires that the measurement falls within the scan itself TIMEOFF=90 is ! used. This will displace the measurement 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. Alternatively, ! you may set TIMEOFF to 0 and use the option 'OFFSET' in ANTAB instead to ! increase the effective length of the scans. In many cases - especially when ! there are Tsys at both ends of the scan - this 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. ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! ! !
