[DAF68] (De Vaucouleurs+Angione+Fraser, 1968)
Write:<<[DAF68] A>>
<<[DAF68] AN>>
<<[DAF68] AW>>
<<[DAF68] AW-W>>
<<[DAF68] AA>>
N: 24
Object:Knot  (SIMBAD class: PartofG = Part of a Galaxy)
Stat:is completely incorporated in Simbad
Note:Structure of the jet in M 87.
Since 1956 (see [B56]), and along the years, N=11 knots are defined, (Nos A-K), knots B, C and G being divided into 2 components (Nos B1-B2, C1-C2, G1-G2), with B2= K and [DAF68] A to C = [B56] A to C.
N=1 Filament (No. L), and the nucleus or central source (No. S).
Knot [DAF68] D has 3 components (Nos DE, DM, DW), N=1 sub-component to DE: DE-W, and N=1 Chandra X-ray component DX.
The HST has permitted to add new knots, [PBZ99].
in source:M 87 = NGC 4486 = Virgo A
