Astronomy lab report abstract

  1. Hey guys,
    I'm in the middle of writing a lab report and I'm having trouble with my abstract. I know as a 3rd year uni student I should know how to write one by now. I feel it's a bit long, what do you think? How could I improve? I'm not asking you to write it for me just some hints.
    The experiment is 'Radio Astronomy of Pulsars' (check out CLEA for more deets)

    'In this experiment the periodic signal produced by a virtual radio telescope is used to find and compare ages, pulse height and distances of pulsars. By finding the time periods of pulsars rotations it is possible to then use this information to find the age. In general, the slower the period the older the star is. Using this, it was shown that relatively 0531+21 is the youngest pulsar that was tested with 2154+40 being the oldest. Next, the pulse height is investigated to see how this varies with frequency. It was shown in graphical form that pulse height decays exponentially as the frequency increases. Interstellar dispersion, via use of the virtual radio telescope, leads to the ability to calculate the distance between the Earth and a pulsar. The method leads to a distance of 2184 ± 2071 pc to 0628-28 and 110.8 ± 98.6 pc to 0531+21. Relating this to calculations made at CERN, my values agree with these measurements.'

    Thank you!

    Can you drop some sentences?

    The thought is people familiar with this topic will know these concepts and in any event you can describe them in your report.
