Operational requirements table: 

 

Requirement
YES / NO / Not required / MAYBE / GOOD TO HAVE / NUMBERS
Remarks
Duration of the observations1-5 hours for PHI

PHI HRT only + look with EUI/Ly-alpha chromosphere

+ SPICE Composition mapping (Action Alessandra)

+ METIS/FLUCTS but not at the same time (at a coronal hole)

PerihelionYes 
RS windowYesRS only
High latitudeGood to haveLow and high latitude
Solar cycle dependenceGood to have 
Radial dependenceNo 
Linkage scienceNoThe related linkage science should already be included in the solar wind sub-objectives.
Multiple orbitsGood to have 
Far side observationsNo 
Earth observationsGood to have 
EMC QuietNo 
SPPNoUnless they need for their planning.
Instrumentsonly PHI + possibly SPICE, action AG?
