Description:
    We present differential CCD photometry for the high-amplitude delta
    Scuti star V567 Ophiuchi obtained in the Johnson V-band. It was
    observed on 15 nights in two consecutive years in order to resolve the
    long-standing ambiguity related to its secondary period. A frequency
    analysis of almost 5000 individual single-filtered measurements
    resulted in two independent frequencies (f1=6.6879c/d and
    f2=11.8266c/d) with a ratio of f1/f2=0.565. The presented
    photometric data are differential magnitudes relative to the
    comparison star C1 (GSC 00417-01714) from Powell et al.
    (1990PASP..102.1131P)
