[Difx-users] DiFX version for VGOS data correlation {External}

[Geoff Crew]

The issues have to do with the way complex spectra are processed and 
handled in the backends and DiFX.  2.5.4 was created as a stable 
processing release for VGOS until the resources were free to guarantee 
operation in a "current" release.  And fixing this situation requires 
some coordination with the way backends are operated.  I'm not fluent in 
the details.

A 2.7.1 release for the EHT processing of the 2021 campaign is likely to 
occur in the next few months (as the media need to be recycled) and a 
2.7-based release suitable for VGOS was one of the options discussed, 
but I do not know the current plan for VGOS.
