Pointing problems in Rev. A Pointing problems: 15.3, 17.3, 20.9 mrad (3 ) ~ 4-5 FOVs rings are ~ 40 mrad wide at ansa May do radial scans instead

Thermal maps CIRS_007RB_LMP001_PRIME (11.5h) CIRS_009RA_LMP001_PRIME (7h)

A ring
11
A ring coverage Longitude Phase angle (M=morning, D=Dusk) Shadow egress and morning ansa OK (lit) at : spin and thermal inertia Miss ingress of shadow Unlit face: Min T on unlit face, shadow detected ? Vertical structure, dynamics
12
B ring
15
B ring coverage Phase angle (M=morning, D=Dusk) Shadow egress and morning ansa OK (lit) at : spin and thermal inertia Unlit face: Min T on unlit face, shadow detected ? Vertical structure, dynamics
16
C ring
19
C ring coverage Phase angle (M=morning, D=Dusk) Shadow egress and morning ansa OK (lit) at many unlit face : thermal inertia, spin better constrained
20
Redesign with CIRSCAN Developping ring analysis software Data base: –Obsname in DB –Nav kernels in DB used for the pointing
