CA and PA explained?

[bennett999]

Please could someone quickly explain CA and PA on the editor. When I made my galacticos database not all the stats that I entered stayed the same, some got higher and some got lower. What would I have to enter in the CA and PA fields to keep the stats the same as I entered in the editor?
