7. Notes to individual galaxies

NGC 2366. The galaxy has an irregular, clumpy structure. The clump in the lower right part of the galaxy has a separate number in the PGC catalogue, LEDA 93088. However, it may also be a star formation region belonging to NGC 2366. Both of the objects are measured together in the present work.

UGC 4459. A light from a bright foreground star appears at the upper left corner of the image (see Fig. 1).

UGC 4483. The estimates of the total magnitudes for this galaxy contain large uncertainties due to a bright nearby foreground star.

UGC 5086. The galaxy measurements have poor calibration because of atmospheric extinction.

BK 3N. The M 81 boundary appears at the upper left corner of the image (see Fig. 1).

Holmberg IX. According to our measurements, this is one of the bluest galaxies of the sample with B-V = 0.22. However, it is possible that the result is affected by the bright neighbor M 81.

UGC 7321. This is an edge-on galaxy of big diameter. For the case of this object the method of obtaining an azimuthally averaged profile can probably yield satisfactory results only in the central parts of the galaxy.

NGC 5229. This is also an edge-on object of big diameter. The same notes as for UGC 7321 can be given.

NGC 5474. This bright spiral galaxy has a very asymmetric structure. The geometric center of the galaxy was used when measuring total magnitudes and surface brightness profiles.

NGC 6946. The CCD field is probably too small for this galaxy. Therefore, the given total magnitudes should be taken as lower limits.
