Correct Labeling of Seyfert's Sextext galaxies

[morsie]

All,
I was going through the 300+ PGC galaxy designations I had in my DB assigning them to older catalogs if there was a reference. NGC followed by IC followed by... I came across my entries for Seyfert's Sextet and doubled checked on-line to see how my astronomy programs compared to the NGC 6027{A,B,C,D,E] assignments. Well, it seems the labeling is all over the map. The best I can determine there are only 4 galaxies interacting and there is a more distant tidal tail taken as another galaxy and a very distant line of sight member. Has anyone ferreted out the correct labeling for these?

I've enclosed a few variations here.

Might be worth you reading Harold Corwin's historical notes which might explain some of the confusion. See http://haroldcorwin.net/ngcic/index.html

Megastar, NED and SIMBAD all agree:
6027 = PGC 56575
6027A = PGC 56576
6027B = PGC 56584
6027C = PGC 56578
6027D = PGC 56580
6027E = PGC 56579
The questionmark is whether those databases need correcting.
