    Dear Chris, and colleagues,

    Using the calibration zero point based on the standard star observations
    with Suprime-Cam on the Apr.10th (probable errors of +-0.1-0.2mag),
    the i'_AB magnitude of S02-032 on the Apr.10th was 23.98mag, which corresponds
    roughly to Ic_Vega = 23.5 mag.
    The i'_AV magnitude of S02-032 on the Apr.10th was 24.78mag, which corresponds
    to Ic_Vega = 24.3mag.
