Hi Oleg What is the source for the photometry in your M67 UBV photometric catalog? This has the potential to be a very useful catalog since many observers use M67 data to calculate their transformation coefficients.
Another CDC catalog that would be very useful to photometric observers would be a catalog of Landolt Standards if somebody would like to take it on.
