CCD and IR photometry of intermediate-age Magellanic Clouds clusters.

The clusters of the Magellanic Clouds (MCs) are studied with a complete dataset for the intermediate-age clusters to determine the integrated colors and spectral energy distribution of the distant galaxies. Observations of a wide sample of MC clusters are conducted in different spectral bands with attention given to the range in which observed integrated color variations were most evident. The CCD and IR photometric data are reduced, and color-magnitude diagrams are given for 9 clusters in V and (B-V) and for 9 clusters in the the IR bands. The observational data yield important clues regarding the extension and lifetime increase of the RGB and the evolutionary status of the clusters. The RGB evolutionary phase transition and an increase in the number of evolved giant stars are found within the age range where the MC clusters show a color change.
