1 ANGULAR RESOLUTION OF CTA AS AN INTENSITY INTERFEROMER
Assumed planetary transit across the disk of Sirius Stellar diameter = 1.7 solar Distance = 2.6 pc Angular diameter = 6 mas Assumed ”Jupiter” with rings D= km, disk = 350 µas CTA array spanning 2 km; Resolution 50 µas at  400 nm provides more than 100 pixels across the stellar diameter

2 ANGULAR RESOLUTION OF CTA AS AN INTENSITY INTERFEROMER
Assumed planetary transit across the disk of Sirius Stellar diameter = 1.7 solar Distance = 2.6 pc Angular diameter = 6 mas Assumed ”Jupiter” with rings Equatorial diameter = 350 µas CTA array spanning 2 km; Resolution 50 µas at  400 nm provides more than 100 pixels across the stellar diameter
