What do the time frames (in parenthesis) mean?

Can you please clarify...

Is it the time frame in which the bulk of player's career occurred?

Is it the time frame in which the player started his career?

Is it the time frame in which the player retired?

A player (like Nolan Ryan, for example) could fall into the "Golden era" "Modern era" or "Today's Game", unless those dates are clarified.

And how would they classify a player who's contributions transcend his playing days (such as Lefty O'Doul, Gil Hodges and the like...)

Thanks in advance for clarifying,
Mark
