Display related fields in the author.php

Hello,

I’ve created a extended user pods with fields and related fields.

In the author.php I’m writting for display the fields:

$nombre_del_autor = get_the_author_meta('nombre');
$nickname = get_the_author_meta('nickname');

echo 'Nombre del autor: ' . esc_html($nombre_del_autor) . '';
echo 'Nick: ' . esc_html($nickname) . '';

What’s the code for the related fields and his fields in the way of use in the templates?

[each coleccion]

<a href="{@permalink}">{@post_title}</a>&nbsp;&nbsp;/&nbsp; Editorial: &nbsp;{@isbn-13_ed} &nbsp;/&nbsp; Idioma Original:&nbsp; {@idioma_ed} &nbsp;/&nbsp; A?o:&nbsp; {@ano_ed}  &nbsp; &nbsp;<hr>

[/each] 

Thanks
