hops::MHO_DiFXZoomBandRebuilder Class Reference

Creates new $FREQ/$BBC/$IF VEX sections for stations that DiFX correlated via zoom bands (zoomFreqId/zoomBandFreqId rather than the recorded-channel tables). The source VEX describes the recorded channels, but the visibilities DiFX emits are from the zoom freqs. Without this rebuild, chan_def lookups during channel naming would fail to match the visibility data (not a big deal for fourfit4, but it is for fourfit3). One synthetic freq/bbc/if triple is created per station per scan and the station's $MODE links are repointed to the new tables. More...

Detailed Description

Creates new $FREQ/$BBC/$IF VEX sections for stations that DiFX correlated via zoom bands (zoomFreqId/zoomBandFreqId rather than the recorded-channel tables). The source VEX describes the recorded channels, but the visibilities DiFX emits are from the zoom freqs. Without this rebuild, chan_def lookups during channel naming would fail to match the visibility data (not a big deal for fourfit4, but it is for fourfit3). One synthetic freq/bbc/if triple is created per station per scan and the station's $MODE links are repointed to the new tables.

Used only when HasZoomBands() && WantZoomChannels() – i.e. the DiFX input declares zoom freqs and the user hasn't explicitly asked for a different (native) bandwidth via -w.
