Angular packages loaded, but I don't use it

Hi,

App is using Blaze, but versions file contains:

...
angular:angular@1.4.8
angular:angular-animate@1.4.8
angular:angular-sanitize@1.4.8
angularui:angular-ui-router@0.2.15
...

I believe some of the packages depends on angular. How to quickly find out which package is it?
