Hodge, P

Stellar associations in the Sc galaxy NGC 2403 are identified and compared to similar samples in Local Group galaxies. Their properties, including the total number delineated, their sizes, the average number of supergiant stars they contain, and their radial distribution are tabulated and are shown to be similar to those of M33 and the LMC. The stellar associations have an exponential radial-density distribution, the scale length of which is 2.0 + or - 0.2 kpc, which is the same as that of the H II regions, larger than that of the blue background galaxian light, but considerably smaller than that of the H I distribution. 19 references.
