摘要：

Accurate and deep BVI CCD photometry is presented for the core regions of six southern compact open clusters (supplemented in one case by U and R bands), which generally have only scanty photometric data published, in some cases only photoelectric or photographic. Together with adoption of modern reference isochrones, this has allowed us to derive improved values for their distance, reddening, age and main sequence morphology.
