Hi Kirill - thanks for the suggestions on this. As you may know, I am working well outside my area of expertise here, so the help is very useful to me.

From your description, it sounds as if "NB:/ZAND" would be a good way to go. Annoyingly, the column field width is one byte too short for that. I dislike ignoring bits of information just to pack everything into the field, but will probably have to do that. Extending the field would break a lot of code that currently processes that list.

I'd think we could classify it as "NB:", and then change galnovae.err to remove this comment :

V407 Cyg re-erupted 2010 Mar 10.

to say, instead (borrowing from your comment),

V407 is a symbiotic binary (Mira red giant donating to a white
dwarf primary).  It had a classical nova eruption on 2010 Mar 10.  See

Does that sound right to you?
