Appendix A:

This contains maps of the B-R isochromes (full lines) and B isophotes for most of the galaxies in the present sample, at least if the data was of acceptable S/N ratio. A few maps of poor S/N were included if thought to convey some useful information. Since the HRCam has to be rotated to get both the object and the guiding star in the field, the approximate direction of the North is given in the captions. No image reversal occurs, so that the East is always 90$^\circ$ counterclockwise from the North.

 

Figure A1: NGC 0584: diE. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.475-1.60 (0.025). B isophotes: 17.0-19.0 (0.5). The flattening of the isochromes, and their shift along the minor axis, suggest dust concentration in the disk

 

Figure A2: NGC 0596: diEp. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.57-1.62 (0.025). B isophotes: 17.2-19.7 (0.5). The slightly tilted, low contrast red pattern, suggests only little dust. Possible blue core feature

 

Figure A3: NGC 0636: diEp. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.525-1.575 (0.025). B isophotes: 17.0-19.0 (0.5). The colour pattern shows a central blue feature, which seems not to be due to inadequate PSF matching

 

Figure A4: NGC 0720: unE. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.58-1.595 (0.015). B isophotes: 18.0-19.5 (0.5). The colour distribution of this flat core galaxy is also remarkably flat. See also Fig. 9

 

Figure A5: NGC 0821: diE. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.675-1.725 (0.025). B isophotes: 17.5-19.5 (0.5). A low contrast red lane nearly along the minor axis is the notable feature of the modest dust pattern

 

Figure A6: NGC 1052: diE. Positions in $^{\prime\prime}$. N at 9 o'clock. B-R isochromes: 1.60-1.80 (0.025). B isophotes: 17.2-19.2 (0.5). The object presents a complex dust pattern with a prominent lane near the minor axis
