Twenty Thirteen get_sidebar Question

Here is a list of all the get_sidebar() calls from the TwentyThirteen files:

• taxonomy-post_format.php: <?php get_sidebar(); ?>
• search.php: <?php get_sidebar(); ?>
• single.php: <?php get_sidebar(); ?>
• archive.php: <?php get_sidebar(); ?>
• index.php: <?php get_sidebar(); ?>
• page.php: <?php get_sidebar(); ?>
• tag.php: <?php get_sidebar(); ?>
• category.php:<?php get_sidebar(); ?>
• author.php: <?php get_sidebar(); ?>

and

• footer.php: <?php get_sidebar( 'main' ); ?>

Hope this helps …
