Re:HARO 01
4.1.12. Haro 1
This object has regular, almost circular outer isophotes, perturbed in
our contour map by the presence of foreground stars, three to the east and
a bright one to the northwest. The inner contours are roughly rectangular
in shape, surrounding a large and very irregular nucleus. Two small clumps
appears to the northeast and to the south of the nucleus. It has been
defined as a paired galaxy with little - if any - tidal disturbance
(Schneider & Salpeter 1992). Its companion is UGC 3937, with a redshift
difference of only {DELTA}v = 210 km s^-1^ and a projected distance of
350 kpc.

Re:HARO 01
4.3. Haro 1
Haro 1 is described (Schneider and Salpeter, 1992) as a paired galaxy with
little or no tidal disturbance. Its companion is UGC 3937, with a redshift
difference of {DELTA}v=210 kms^-1^ and a linear separation of 350 kpc. Van der
Burg (1985) reports on a possible detection of a third companion in H I at
07h33m54s, +35^deg^46'. The B-band image (Fig. 4a), reveals a large irregular
nucleus, whereas in H{alpha}, at least 6 distinct clumps are discernible. The
X-band map (Fig. 4b) shows the radio emission to be peaked at the second and
third strongest H II regions near the center of the disk and the eastern and
southern H II regions can be seen as local maxima of the radio emission. The
galaxy's star forming regions appear to suffer high extinction, as its B-R
color of 0.85+/-0.03 is very uniform and gives no suggestion of concentrated
starforming activity.

Re:NGC 2415
NGC 2415 (Haro 1); Irr pec, BCG.
NGC 2415 is in a compact group, with three companions situated about 22'
(0.5 Mpc) north, but this galaxy shows no evidence of morphological
disturbance (van der Burg 1985). This blue compact galaxy is slightly
ellipsoidal, with an irregular core and irregular nebulosity (Gordon &
Gottesmann 1981). NGC 2415 has a blue magnitude of M_B_ = -21.0 and a
neutral hydrogen content of ~6% of the total mass of the galaxy (Gordon &
Gottesmann 1981). Its far-infrared (FIR) luminosity is high
[log (L_FIR_/L_sun_)~ 11.1; Iyengar, Rengarajan, & Verna 1985], probably
owing to the presence of an intense burst of star formation and to the
presence of dust. If dust is present as these authors suggest, it is
either lacking in the 2200 A feature seen in Milky Way reddening curves,
or else the dust is possibly very clumped. The short-wavelength IUE
spectrum has been discussed by Fanelli et al. (1988) and analyzed using
spectral population synthesis. The UV spectrum is rich in absorption
features and shows the presence of OB supergiants together with a
composite population of O, B, and A stars. The spectral synthesis models
suggest that star formation took place in discrete episodes rather than
in continuous formation, with the last episode arising about 10 Myr ago.
