Undocumented ST calibration values

Question asked by stevenhoneyman on Nov 7, 2015
I'm learning to use the ADC in an F2 device. I was looking for the "proper" way to calculate values rather than making any assumptions like every single tutorial or example code that I've seen so far. One useful finding appears in this git commit, but I can't find any documentation for it, and it isn't in use anywhere else that I've seen.

(note that the commit comment isn't fully correct - my F2 does have these at the same addresses as the F4)

Did I overlook this in the reference manual somewhere? Search doesn't always help as they might be written with a space in the middle, or in a table, etc.
