## Notes for object NGC 4179

### 5 note(s) found in NED.

 1. 2007MNRAS.378..594P 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. 2. 1994CAG1..B...0000S Re:NGC 4179 S0_1_(9) (P) CD-2102/2103-S March 18/19, 1982 103aD + GG495 45 min 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. 3. 1994A&AS..105..481M Re:NGC 4179 NGC 4179: A regular edge-on S0 with inner ring and thD envelope. 4. 1973UGC...C...0000N Re:UGC 07214 S0 (de Vaucouleurs) 5. 1964RC1...C...0000d Re:NGC 4179 Classification uncertain: possibly E+7
