Notes. (a)Coordinates of the adopted fields centre (epoch J2000, as for all coordinates in this paper). (b)Field size in arcminutes. (c)Field position angle (in degrees east of north). (d)Fields NGC 2071 and NGC 2068, fields NGC 2023 and NGC 2024, and fields L 1641-S (1)–(4) were combined into larger fields during data reduction. (e)First coverages taken with a position angle of 5°.
