Find resolution and size of telescope dish.

  1. Mar 28, 2010 #1
    1. The problem statement, all variables and given/known data

    From the shape of the Sun’s emission in the plot, estimate the resolu- tion of the telescope (the full width half maximum of the Gaussian shape) and from this calculate the size of the dish.


    The sharp bell represents the sun's emission and hydrogen is used as the element (21 cm hydrogen line)

    2. Relevant equations

    angular resolution= wavelength/diameter

    3. The attempt at a solution

    Since the x-axis is in modified julian date, I'm not sure if I took the half maximum correctly, as I got around .016 distance in mjd, which means a diameter of around 13 m.
