    22Nov2018 : Briefbrief exchange with J. Anderson (RA-DiFX) on patching closed-loop delays into DiFX CALC model .im files

    17Dec2018 : Testtest data set RK18CJ received at Bonn, no documentation

    07Jan2019 : Firstfirst look at raw data and .vex; created v2d and vex.obs; ground-only, no fringes yet in K nor C band; no station clock infos

    15Jan2019 : Createdcreated 'raPatchClosedloop.py' script to apply closed-loop corrections to DiFX/CALC IM prior to running actual DiFX correlation job. Script in DiFX Trunk ./sites/MPIfR/oneoff/

    ...

    09May2019: Revisited the dual-band VEX file. Shifted GBT (former ref ant) and other K-band ground stations +17.20 us. Got fringes now both K and C, both in coherent and in rubidum. Improved raPatchClosedLoop.py to allow a residual rate to be fed back to the polynomial. Tried the suggested -3.0e-10 sec/sec rate offset to no avail, rates already low before that.
