Where Is The Code That Assigns Data To The Filters Block?

Hi, what is the php code assigns the data to the product filters block? Meaning the array that has feature ids, variant ids, etc. that is used in /design/themes/responsive/templates/blocks/product_filters/original.tpl?

I want to put a value in the variants part of the array that I will use in the tpl file when the values are for eached.

Is it a frontend controller, is it a hook, is it a function in one of the fn files?

Check fn_get_filters_products_count (app/functions/fn.catalog.php)

That was exactly it, you've saved me again, thanks!!
