Abstract:
We present CCD VIKC photometry down to V∼21mag in the field of the
rich open cluster NGC 2194, which is projected towards the Galactic
anticentre direction. We measured V magnitudes and V-I colours for a
total of 2515 stars in a field of 13.6x13.6arcmin2,
supplemented with CCD photometry in the C, M and T1 filters of the
Washington system and photoelectric CMT1T2 photometry of 20 red
giant candidates, using the 0.9-m telescope at the Cerro Tololo
Inter-American Observatory (CTIO), Chile, on 1997 December 23-24.
