    C172C Correlation Report

    General information

    • Session info: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/
    • Station feedback: http://www3.mpifr-bonn.mpg.de/div/vlbi/globalmm/sessions/sep17/feedback_sep17.asc
    • C172C consists of only one subproject: MM012.
    • Initial correlation was started with all stations and done up to and including scan No0126, second correlation (fixing Effelsberg incorrect channel order) was done without Mh and the KVN stations due to local cluster data loss and these stations having deleted their own copies of the data. Final version is a combination of these two correlations, with non-Ef baselines taken from the initial correlation and Ef baselines -- from the later one with Mh and the KVN stations missing. Thus there are no Ef-Mh baselines, and Mh is only present up to and incuding scan No0124. Since the KVN stations were starting later in the experiment than scan No0126, they were lost completely.

    Notes

           Precorrelatyio

    • OV - in the beginning only two modules (JOD+0090 JOD+0096) arrived, containing scans up to No0232, 10nov17 P. Perley confirmed a third OV module was found and it was sent to MPIfR.
    • KVN : some fringes inside KVN within +-32usec and +-1sec; station positions and freq setup appear correct
    • KVN Ky : transferred files are those of Ulsan rather than Yonsei (retransferred)
    • KVN Kt : no fringes (asked for operator log files, the automatic log files show no error)
