6. Is the Crab Pulsar Showing A 60-second Periodic Modulation?
... 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 . ...

17. Towards Optimal Analysis of HST Crowded Stellar Fields
... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...
