Reduce padding on header image in studio theme

I have created using the studio theme.

I have uploaded a header image at 980px x 100px

In the studio-child folder, in the _inc folder, in the css folder
I have file studio.css.

I have placed all the code in here from the parent studio.css file.

I am editing the code to make some changes and I was hoping to be able to reduce the padding under the header image.

I have reduced a number of padding values, including the header wrapper and header logo & font.

However I can't find the line of code to reduce the header padding below the image.

Can anyone help?
