Comparison of V magnitudes measured with the OM and from the literature for optical counterparts to EPIC sources in Collinder 69: filled symbols – C 69 E, open symbols – C 69 W. The good agreement shows that OM photometry is reliable and that the errors associated with the transformation of instrumental into standard magnitudes for the C 69 W field are negligibly small.
