Re:MRK 0731
The two sources in Mrk 731 are separated by a projected distance of 250
pc along the major axis with the galaxy at a distance of 17 Mpc. Figure
21 is the spectrum of a and b and gives a velocity difference of 30 (+/-
14) km s^-1^ with source b having the larger redshift. The spectra show
the two nuclear sources to be very similar, both in the continuum level
and in line ratios. The H{alpha} flux in source a is 1.8 times that in b.
