Re:NGC 4179
See Pohlen et al. (2004b) for additional notes. We find that the
face-on-equivalent profile of NGC 4179 is well described as a Type II with an
inner shallow exponential (of h_in_ = 30.9 arcsec =1.4h_out_) and an outer
slightly steeper exponential (h_out_ = 22.6 arcsec) with a break at a radial
distance of R_br_ ~= 98 arcsec =3.2 h_in_ and at a surface brightness of
{mu}_br_ = 23.3 V-mag arcsec^-2^.
In the inner disc we find an increase in scalelength of 36 per cent between
the major axis and 4.5 times the thin disc scaleheight (6.1 arcsec) reported by
Pohlen et al. (2004b). Overall the scalelength increases by a factor of 1.8 to
the highest measured cut at z = 45 arcsec. This is very similar to the factor of
1.9 reported by Pohlen et al. (2004b) for the ratio of thick to thick disc
scalelength, obtained with a completely different method (3D model fitting).
Their thin disc scalelength of 26.2 arcsec is almost identical to our
scalelength of 26.7 arcsec at the major axis. Our scalelength of 46.8 arcsec for
the vertical cut with the largest distance from the plane (at z = 45 arcsec) is
~=9 per cent smaller compared to their thick disc scalelength of 51.0 arcsec,
which we may reach for cuts even higher above.

The inner and outer disks in NGC 4179 are
well seen in the main print and the insert. Note
the much greater extent of the outer disk in the
main print, using the star near the right-hand
part of the major axis as a position marker.
