Deep CCD surface photometry of the edge-on spiral NGC 4244

We have obtained deep surface photometry of the edge-on spiral galaxy NGC 4 244. Our data reliably reach 27.5 R magnitude arcsec(-2), a significant imp rovement on our earlier deep CCD surface photometry of other galaxies. NGC 4244 is a nearby Scd galaxy whose total luminosity is approximately 1 mag f ainter than the peak of the Sc luminosity function. We find that it has a s imple structure: a single exponential disk, with a scale height h(Z) = 246 +/- 2 pc, a scale length h(R) = 1.84 +/- 0.02 kpc, and a disk cutoff at a r adius R-max = 10.0 kpc (5.4 scale lengths). We confirm a strong cutoff in t he stellar disk at R-max, which happens over only 1 kpc. We do not see any statistically significant evidence for disk flaring with radius. Unlike the more luminous Sc galaxies NGC 5907 and M 33, NGC 4244 does not show any ev idence for a second component, such as a thick disk or halo, at mu(R) < 27. 5 mag arcsec(-2).
