... We Fourier analysed Hubble Telescope Crab pulsar data obtained with the High Speed Photometer in October 1993. A weak modulation at frequency Hz is detected. We found a strong correlation between this result and the Fourier transform result of stroboscopic Crab pulsar data obtained in December 1994 at the 1.82m telescope of Asiago observatory (University of Padua, Italy). ... We found that both data show a weak modulation at the period of 60 seconds. ... The corresponding frequency is Hz . ...
