# Stargazing Accelerating universe - luminosity data

I am looking for the measurement data for distant objects (e.g. type Ia supernovae)
The red shift and the luminosity flux data.
What time interval is used in the luminosity flux measurement?
What formula is used for the luminosity distance calculation?

Hopefully you realize that this is a huge topic and that people spend their careers on the questions you raise. However, having said that, the web site below might be a good place to start. The 'CSP Publications' tab has some good review articles, and the 'Data' tab has access to some of the data.
