the slew marker "HV Above/Below Requested" occurs at 14:14:10.30 and was dealt with at 14:14:12.26 with "DCS aborting" about 2s later which is greater than the 300ms telecommand processing implied requirement.

A test was run on the fully patched code which involved a bad worst case of 10s of stars which would have done a "bright star store exhausted" if the problem was stil pr4sent. This is the relevant part of the log where even 10s of stars couldn't stop a slew. The bad checksum 1 1 1 is a marker added to the Ada code at the arrival of a slew request.
