Holmberg의 은하 직정과 SUGC에 있는 de Vaucouleurs face-on 은하 직경과의 차이는 BGC와 Holmberg 목록으로 Heidmann 등이 구한 차이보다 더 적게 나타났는데, 이는 펑균표면광도 $\mu_B$ = 24.5 등급에서 구한 face-on 은하 직경을 수록한 BGC 자료들을 H eidmann 등이 사용했기 때문이다. 또, 본 논문에서 구한 Holmberg 은하 직경과 de Vaucouleurs은하 직경과의 상관관계식에서 $D_h>D_v$로 나타났으므로 Holmberg 은하 반청 $b=\frac{1}{2}D_v$로 사용하는것이 옳지 않다고 본다.

Holmberg's diameters of galaxies $D_{h}$ were obtained from Holmberg catalogue. The difference between Holmberg's diameter and de Vaucouleurs' face-on diameter is campared with the results of Heidmann et al. The difference obtained in this paper is smaller than that of Heidmann at al. Also, the correlation between $D_{h}$ and $D_{v}$ was obtained for each type in de Vaucouleurs' classification of galaxies. It shows that $D_{h}$ is overestimated that $D_{v}$.
