Hi everyone,
First time posting, sorry if this is in the wrong format or wrong place. For a project in a cosmology course I need to find the Hubble constant from from time delay in a gravitational lens. the one we are using is QSO 0957+561. My question is how to I find the time delay from a set of data containing the flux densities (for each of the two images the lens created) and the julian day for each data entry?
thanks
ps please let me know if I need to be more specific in this question.
