This refers to a dissenting opinion draft, including dissents from denial of certiorari if in opinion form

Memos where a justice expresses the inclination to join a dissenting opinion, including joining the dissent in part; memos may also state a justice’s intention to join a dissent if another justice writes or circulates one; memos may also state that a justice expects to join or tentatively joins a dissent

Memo states includes a justice's suggestion for a separate opinion (e.g., don't agree with reasoning of separate opinion; comment on separate opinion; will join separate opinion if; cannot join separate opinion; will be making suggestion to separate opinion). The identity of the separate opinion author who receives suggestion is located in the JOINED variable.
