Scientific paper

Emission from discrete sources dominates the X-ray luminosity in spiral galaxies. We propose to survey a sample of nearby spiral galaxies to characterise the properties of the discrete sources. We have chosen nearby, face-on galaxies which span the Hubble sequence for spirals. Chandra's superb imaging capability will allow us to detect sources down to a luminosity of 4e36 erg s^-1 in the ROSAT band. We aim to classify souces as accretion powered binaries (Low or High Mass) or supernova remnants. Our survey will go more than a factor of 20 deeper than the deepest ROSAT pointings of the same galaxies. This data will enable us to look for trends in the characteristics of discrete sources with Hubble type, metallicity and stellar population.
