This will be investigated. Note that the roll offset of 0.025 degrees corresponds to a linear displacement of 0.43 arcsec over a lever-arm of 1000 arcsec (typical guide star distance). In other words this is not a large offset. - ACE soft proton rates are very low and steady. Snapshot -------- Slight violation of snapshot roll limit. See above.
