Samenvatting
We present optical and near-infrared archival observations of eight
edge-on galaxies. These observations are used to model the stellar
content of each galaxy using the FITSKIRT software package. Using
FITSKIRT, we can self-consistently model a galaxy in each band
simultaneously while treating for dust. This allows us to measure
accurately both the scalelength and scaleheight of the stellar disc,
plus the shape parameters of the bulge. By combining these data with the
previously reported integrated magnitudes of each galaxy, we can infer
their true luminosities. We have successfully modelled seven out of the
eight galaxies in our sample. We find that stellar discs can be modelled
correctly, but we have not been able to model the stellar bulge
reliably. Our sample consists for the most part of slowly rotating
galaxies and we find that the average dust layer is much thicker than is
reported for faster rotating galaxies.
