Wasn't it the other way around? A type of supernovas ("standard candles") were discovered before the expansion and used to discover the expansion? The formula for distance only uses absolute and apparent magnitudes to calculate distance?

Yes, my comment above is wrong. It was the other way around.

Yeah they calibrated red shift from standard candles.

They use luminosity for SNe Ia.
