Description:
We present UBV photometric observations of 55 wide visual double stars
with K- and M- type primaries. Our observations have been compared and
combined with information available in the literature. At least 58% of
them are optical pairs.

Note (1): PHY: physical pair
PHY(?): probably a physical pair
PHY?: either has CO components only, or they are in addition
gravitationally bound
CO?: two components of the system have common origin (born together,
but not orbital motion)
CO(?): either OPT or it has CO components
OPT: optical pair
