Opportunity implementation in geo-pipeline:
Double transit in front of Jupiter, within specific resolution constraints -

;;Janus FOV is 2000 pixels x 1500 corresponding to 1.72 deg x 1.29 deg which is approximately 8.5e-4 deg opening angle per pixel
;;If we take 1% of the pixels to be covered at minimum, we should have 1/100*2000*8.5e-4 as minimum angular size for the moon
;;angular diameter
MINIMUM ANGULAR RESOLUTION= (1./100)*2000*8.5e-4 deg

-Angle SC-JUP/SSC-MOON1 < jupiter angular radius
AND
--Angle SC-JUP/SSC-MOON2 < jupiter angular radius
AND
--SC-MOON1 distance < Distance to Jupiter
AND
--SC-MOON2 distance < Distance to Jupiter
AND
--MOON1 angular size > JANUS MINIMUM ANGULAR RESOLUTION
AND
--MOON2 angular size > JANUS MINIMUM ANGULAR RESOLUTION
