Before Convergence Adjustments

[VA561]

I am in the process of performing the static and dynamic convergence adjustments on a 1960 RCA roundie. It has a ct-11 chassis. I recently purchased a book titled RCA Color TV Troubleshooting pic-o-guide. It is very helpful in guiding you through the static and dynamic adjustment process. In the book it says to check Size, Linearity and Centering before any of the convergence adjustments are touched. My question is this ; is there a standard or preferred method of performing the size, linearity and centering adjustments? I have a BK color pattern generator that I use to produce an 11x7 crosshatch pattern for the dynamic convergence adjustments. It also has a 1x1 crosshair pattern. Any input as to the size linearity and centering methods would be greatly appreciated.
