Sorry, CAESAR II doesn't print out the <em>classic</em> participation factor. Instead, the program is actually printing what is known as the <em>mode coefficient</em>.

For a given mode, the <em>mode coefficient</em> is defined as: the participation factor (for that mode) times the acceleration from the response spectrum (for the frequency of that mode) divided by the frequency squared (for that mode).
