hops::MHO_DiFXOvexPatcher Class Reference

takes care of all the wierd structural fix-ups that turn a freshly-parsed VEX json into the special OVEX flavor the HOPS3 ovex parser will accept. Needed to make fourfit3 happy reading the root.json produced by difx2hops -k. Does the following: More...

• stamp $EXPER.exper_num and target_correlator = "difx"
• clear $DAS and station $DAS links (HOPS3 ovex can't parse them)
• assign mk4_site_ID for every $SITE and build the DiFX-uppercase -> VEX-case station code / name maps consumed downstream
• wrap $ANTENNA.axis_offset in the {axis_type, offset} struct
• link $STATION entries to their $CLOCK keyword
• synthesize $TRACKS from datastream quantBits and relink $MODE.$TRACKS
• link $GLOBAL.$EOP to the first $EOP (or a dummy)
• delegate zoom-band $FREQ/$BBC/$IF synthesis to MHO_DiFXZoomBandRebuilder
• rewrite chan_def.phase_cal_id to match the station's $PHASE_CAL_DETECT (if not then fourfit3 do_phase_cal_detect.c aborts)
• stamp the boilerplate $EVEX/$CORR_INIT/$LOG/$PBS_INIT junk that HOPS3 expects
