What is the purpose of putting a capacitor on the primary side of a step-down transformer?

I''m looking at this design For a split supply. I get that the thermistors are there to limit the inrush current, but I don''t understand the purpose of C9 and how its value was chosen. In addition to Autistic''s correct answer, the value of C9 (X rated) is a compromise between consuming excessive AC current at 60 Hz while suppressing the …
