... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...

... 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 . ...

An extra leap second has to be inserted at the end of 2008, so this is how you should count down on New Year's Eve to celebrate the start of the International Year of Astronomy according to Irish astronomers. The extra second is needed to bring the uniform measure of time used by physicists using atomic clocks back into nearly exact agreement with time as measured by the rotation of the Earth. ...

The basic concept is to correct the speed of the drive motor to compensate for the fact that the worm drives the worm wheel a bit faster or slower as it rotates.  This is done by going into a training mode and manually training the computer to compensate for the mechanical defects.  ...
