DE equation of state parameter

  1. Aug 28, 2009 #1
    1. The problem statement, all variables and given/known data
    Plot [itex]\Delta w[/itex] as a function of spectroscopic redshift for some given biases between spectroscopic and photometric redshifts.


    2. Relevant equations
    [itex]\Delta w = \frac{\partial D_{A}}{\partial z}\frac{\partial w}{\partial D_{A}} \Delta b[/itex]

    [itex] D_{A} = \frac{c}{H_0} \cdot \frac{1}{(1+z)} \cdot \frac{1}{\sqrt{\Omega_m (1+z) + \Omega_{\Lambda}}}[/itex]

    3. The attempt at a solution
    I've got the bias curves ready to plug in so I can plot some w stuff here, but I don't know how to relate [tex]\Omega_{\Lambda}[/tex] to [tex]w[/tex]. Can anyone help?
