4. Comparison with Markarian and blue Haro galaxies

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 $M_{{\rm H}}/M_{{\rm i}}$, $M_{{\rm i}}/L$ and $\sigma_{{\rm h}}$ 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 $M_{{\rm H}}/L$. 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 $M_{{\rm H}}/M_{{\rm i}}$ versus $M_{{\rm H}}/L$ plot) displayed in Fig. 4.

Three values of the total indicative mass to luminosity ratio, in solar units, are also indicated along the straight lines

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 ( $\sigma_{{\rm h}}$, $\sigma_{{\rm h}}/a_{0}$, $M_{{\rm H}}/M_{{\rm i}}$, $M_{{\rm H}}/L$ 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 $\sigma_{{\rm h}}$ (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.
