The chart covers everything from the F# below the staff (F#0) to the C above it (C2). The first dot corresponds to the first valve (right index finger), the second to the second, and the third to the third.

The sharp/flat tendencies are of my own personal experience and the result of some of my research; They may not be quite scientifically accurate all the time!
