OSO is up to date with latest architecture decision regarding sky direction representation ADR-63 https://confluence.skatelescope.org/display/SWSI/ADR-63+Sky+direction+representation
and the Holography mapping pattern changes of ADR-106 https://confluence.skatelescope.org/display/SWSI/ADR-106+Defining+a+mapping+pattern
OSO is compliant with the ADR-63 changes.
This is demonstrated through testing using existing OSO test plans.
Changes made do not break backwards compatibility.
