Figure 1: Digital Sky Survey images of 18 galaxies in the Canes Venatici I cloud. The field size is 6 $\hbox {$^\prime $ }$ , North is up and East is left. The HST WFPC2 footprints are superimposed.

Figure 2: Top: WFPC2 images of 18 galaxies: UGC 6541, NGC 3738, NGC 3741, KK 109, NGC 4150, UGC 7298, NGC 4244, NGC 4395, UGC 7559, NGC 4449, UGC 7605, IC 3687, KK 166, NGC 4736, UGC 8308, UGC 8320, NGC 5204, and UGC 8833, produced by combining the two 600 s exposures obtained through the F606W and F814W filters. The arrows point to the North and the East. Bottom left: The color-magnitude diagrams from the WFPC2 data for the 18 galaxies in the CVn I cloud. Bottom right: the Gaussian-smoothed I-band luminosity function restricted to red stars (top), and the output of an edge-detection filter applied to the luminosity function for the 18 galaxies studied here.
