    Fringes

    Station Code Fringes Plots Comments
    Ef B yes

    Fringe overview of all baselines (all of C182A) including this antenna in LL (left for each baseline) and RR (right for each baseline).

    Legend: white - scheduled, but no data, blue - no fringe, dark red/brown/green - fringes of different quality, bright red - false fringe (mostly for baselines to KVN, determined by having exremely large single-band delay, > 0.1us)

    c182c_SBD_RfAnt_Ef_LLRR_AllSrc.pdf

    Same for all antennas below unless otherwise noted.

    		  
    On X yes

    Ys Y yes

    c182c_SBD_RfAnt_Ys_LLRR_AllSrc.pdf

    		 An amplifier burned out just before the beginning of the session, fixed during the fringe test, but after that the antenna consistently produces fringes only to RCP, while in its typical configuration in should have LCP only, duplicated to both channels. But in this session it appears to have RCP only.
    Mh Z yes

    c182c_SBD_RfAnt_Mh_LLRR_AllSrc.pdf

    		  
    Pv P yes

    GLT:
    Gl    		 g yes

    c182c_SBD_RfAnt_Gl_LLRR_AllSrc.pdf

    		 The GLT was observing in an unknown polarization configuration, linear or some elliptic instead of the circular due to a polarizer misalignment. Unless there is a way to recontruct the proper circular polarization, this station must be flagged or used only for the total power measurement.
    VLBA:
    Br    		 b yes

    c182c_SBD_RfAnt_Br_LLRR_AllSrc.pdf

    		 All VLBA antennas suffer from the same problem, diminishing the effective observing time in many scans by 30-50%.
    VLBA:
    Fd    		 f yes

    c182c_SBD_RfAnt_Fd_LLRR_AllSrc.pdf

    Kp    		 k yes

    c182c_SBD_RfAnt_Kp_LLRR_AllSrc.pdf

    		 All VLBA antennas suffer from the same problem, diminishing the effective observing time in many scans by 30-50%.

    La    		 l yes

    c182c_SBD_RfAnt_La_LLRR_AllSrc.pdf

    		 All VLBA antennas suffer from the same problem, diminishing the effective observing time in many scans by 30-50%.
    VLBA:
    Pt    		 p no

    c182c_SBD_RfAnt_Pt_LLRR_AllSrc.pdf

    		 All Pt data for this whole session lost due to a malfunctioning Mk5 module. We attempted to save it, but the data has proven to be unrecoverable.
    KVN:
    Kt    		 t yes

    c182c_SBD_RfAnt_Kt_LLRR_AllSrc.pdf

    Notes

    All VLBA antennas are affected by the same problem (probably originating in the control software) during the whole session: for a significant portion of scans the recording starts several seconds or even few minutes late compared with the schedule. This results in effective reduction of observing time by a factor of 30-50%.

    For some reason fourfit finds a fringe for every baseline including a KVN antenna. We are stiil looking how to avoid this problem. Meanwhile in the overview tables above the value of single-band delay is used to tell the difference between the considerably fewer real fringes and false positives.
