Comparison with other peculiar galaxies (Markarian and blue Haro, in particular)
in the same range of morphological types (Bottinelli et al. 1973a,b; 1975)
presented in Table 3
shows that the variation range of derived parameters for
Kazarian galaxies is practically the same for
,
and
values. Notice that the
units used for comparison are the same as given in Table 1.
In spite of a somewhat
different range of the luminosity and hydrogen mass variation
compared with Markarians, our sample galaxies vary within the
same limits when considering representative ratio
.
By this parameter Kazarian and Markarian galaxies vary in
the same and relatively narrow range compared with blue Haro
objects.
It is worth noting a well known fact that the same values for classical galaxies (Heidmann 1969; Roberts 1969; Balkowski 1973; Shostak 1978; Bottinelli et al. 1982; Roberts & Haynes 1994) do not differ from those for Markarians and Haros (Bottinelli et al. 1973a,b; 1975).
The intermixing of Kazarian, Markarian and blue Haro galaxies is well seen
on the three-ratio diagram (showing
versus
plot)
displayed in Fig. 4.
It is well known that primarily a given normal galaxy of the Hubble sequence has particular parameters corresponding to its morphological type (Balkowski 1973; Bottinelli et al. 1982) and then a second approximation these values are also related to the luminosity.

In the case of Kazarian galaxies (as well as Markarians and Haro blue galaxies)
not all the integral parameters of a given galaxy have the values
expected for a single morphological type. To demonstrate this, we
determined for each Kazarian
galaxy its most probable morphological type expected from the derived
values of the 5 parameters (
,
,
,
and W) following the method described in Bottinelli et al. (1975).
Obviously a good agreement with its classical type is always expected when
this method is applied for a single galaxy.
As a result, we found only 7 galaxies with all above mentioned parameters corresponding to its given morphological type. A mild agreement was found for 5 galaxies and none for the remaining 11 galaxies of our sample.
Taking into account the luminosity effect which leads to the modification of all used
parameters except
(Balkowski 1973) and following the scheme
described in Bottinelli et al. (1975) we finally found that no classical
morphological type can be assigned for 7 galaxies (Kaz 23, 63, 69, 211, 228, 512, 579)
while well defined types for 10 galaxies were obtained.
All this suggests a rather high relative number of Kazarian galaxies (7 out of 23) featuring certain peculiarities. The careful comparative study of their optical and H I properties is needed to clarify the nature of these peculiarities.
In the next section brief comments on the optical properties of some peculiar objects are given.
