2. Observations

JHK images of HV Tau were obtained using PUEO adaptive optics system equipped with the near-IR camera MONICA (Nadeau et al. 1994) at CFHT on Sept. 29, 1996. Monica includes a Nicmos 3 2562 pixel array, with a plate scale of 0.0344"/pixel, yielding a field-of-view of [FORMULA], thus encompassing the three components of the HV Tau system. Since the primary objective of the observational program was to obtain differential photometry of the components in a sample of young binaries, the integration time was limited to 30 seconds in each filter. For HV Tau, the angular resolution on reduced images ranges from about 0.07" in J to 0.13 " in K.
